The Elder Scrolls Feats and Discussion

[Stocking Anarchy]

Miraak has a super impressive feat that got overlooked for all this time. I've never seen anyone else bring this up...

When Miraak absorbs a dragon soul in the final battle, the skies of Apocrypha change colour, temporarily turning from green to yellow. This is from the top of the tower you are fighting on, which is quite tall, and this change in colour spans to the horizon.

Here're a few other versions where they captured the moment better than I did (this effect lasts a few seconds after the dragons soul has finished being absorbed).

On top of this, it's worth repeating that not only is Miraak using multiple Dragon Shouts simultaneously, but he's able to inflict harm on others while ethereal (infact, he outright kills each dragon with a single attack).

 

[Stocking Anarchy]

Spells can be used to destroy someones mind, and fireballs can turn someone to char.

Hiding in the shadows, stalking your prey, liberating items from the unworthy. Some call you scoundrel, rogue, thief! But really, is it any more civilized to stomp stridently around in clanking platemail armor, swinging your claymore at anything that crosses your path, or to destroy a person’s mind with a spell, or to char someone with a fireball?

(From the Oblivion Prima, page 29)

Miraak is corrupting the All-Maker Stones to compel the people of Solstheim to rebuild them and strengthen his own power.

The Skaal of Solstheim revere six Sacred Stones, symbols of their bond with nature and the All-Maker. These places of power are being corrupted by Miraak, who is compelling the people of Solstheim to rebuild them to strengthen his own power.

(Skyrim Prima, page 94)

A new power in the form of an ancient creeping terror is slowly engulfing Solstheim, as Miraak is siphoning the island's All-Maker Stones and enslaving its inhabitants. His power grows, and only the Dragonborn may be able to stop him.

A new power - an ancient, creeping terror - is gradually enveloping the island of Solstheim off the coast of Morrowind. For it seems the long-forgotten tombs and sacred stones are resonating; grasped firmly by the machinations of the first Dragonborn: Scholars tell of a priest named Miraak, who served the dragons with a group of powerful acolytes, before finally turning against his dragon masters, and finding new strength and knowledge under the yoke of the Daedric Prince Hermaeus Mora. Miraak is demonstrating his fortitude by siphoning the island's All-Maker Stones, and enslaving its inhabitants. As his power grows, he has even sent his followers into the provinces of Skyrim in search of the 'false' Dragonborn, the only one who may be capable of stopping his return.

(Skyrim Prima, page 583)

Miraak seeks to siphon the power of the All-Maker stones and has tainted them with evil, compelling the weaker-willed people of Solstheim into constructing strange shrines for this purpose.

The animistic Skaal hold these ancient carved stones to be evidence of their deity, part of a simple cosmology in which the All-Maker created all matter and the world. while these notions may seem primitive to Nords of Skyrim, the magic that courses through these stones is very real-so much so that Miraak seeks to siphon it and has tainted them with evil, compelling the weaker-willed people of Solstheim into constructing strange arched shrines for this purpose.

(Skyrim Prima, Page 584)

Miraak is the first Dragonborn, who long ago may have had a destiny to defeat Alduin, but instead chose another, more selfish path. After escaping into Apocrypha, Miraak has been growing in knowledge and power for centuries, all while awaiting his chance to return.

Miraak was the first Dragonborn. His destiny may have been to defeat Alduin bac in the Mythic Era, but he chose a different path: to use his Dragonbom abilities to gain power for himself. Originally a dragon priest, he was seduced by Hermaeus Mora and secretly became his disciple. He gathered a cult to Hermaeus Mora at his temple on Solstheim.

Eventually, the other dragon priests discovered Miraak's heresy and led a crusade against him. He was defeated, his followers killed or scattered, and his temple razed. But Miraak was able to escape into Hermaeus Mora's realm of Apocrypha, where he has been growing in knowledge and power over the centuries while he waited for a chance to return.

(Skyrim Prima, page 585)

Miraak is siphoning the power of all of the All-Maker Stones, using the enthralled inhabitants of the island to do his dark bidding.

A lengthy subterranean crypt lies under one of the All-Maker stones, where the bones of dragons and recently constructed arches reveal the true extent of Miraak's power. Currently, the construction is built around a central stepped courtyard, where the ancient Tree Stone stands. Miraak is siphoning its power, and stone arches are being constructed by enthralled Reaver and Skaal workers, including Yrsa and Oslaf. Frea is here, hoping to remove the curse that has befallen her people. The completion of the Dragonborn Main Quest is required to remove the trance the Reavers and Skaal are under and cleanse the entire area of Miraak,s influence. After you meet with Frea, you can enter the temple here via a curved path carved into the edge of the courtyard.

(Skyrim Prima, page 1027)

This All-Maker Stone protrudes from the snowy ground northwest of the Skaal Village. Currently, Miraak is siphoning the stone's power, and stone arches are constructed by enthralled villages.

(Skyrim Prima, page 1030)

This is one of the All-Maker Stones, nestled just outside and southwest of Raven Rock. You may meet the Dunmeri mage Neloth here in the initial stages of the Dragonborn Main Quest, before he moves to Tel Mithryn. Currently, the stone's power is being siphoned by Miraak, and stone arches are constructed by enthralled town citizens and Redoran Guards.

(Skyrim Prima, page 1047)

This All-Maker Stone stands near the Dunmer settlement of Tel Mithryn. Currently, its power is being siphoned by Miraak, and stone arches are constructed by both enthralled Reavers and Ulves Romoran from TeI Mithryn (he moves back there once the spell is broken). The Bend Will Shout
is required to remove the trance the Beavers are under (after which, they attack the summoned Lurkers and may be hostile) and to cleanse the stone of Miraak's influence. ln addition to the summoned Lurker once the spell is broken, two additional Lurkers are formed down by the water and encroach on this combat. Beware!

(Skyrim Prima, page 1062)

All of the All-Maker Stones have been consumed by a strange green energy.

NOTE: This Earth Stone is one of Six Sacred Stones to be found on Solstheim. Much like the Standing Stones of Skyrim, they grant great power to those who seek it. However, at the moment, the stones are consumed by a strange green energy. Try to activate any Stone and you will awake to find yourself helping in the construction. You will free the thralls forced to build these shrines for Miraak later in this quest.

Rieklings will destroy the barrels they're hiding by shattering them with enough force to send nearby objects flying (note the plate next to the barrel on the right).

 

[Stocking Anarchy]

Another example of the explosive power of rieklings escaping their barrels.

 

[Stocking Anarchy]

At almost every corrupted Allmaker-Stone site, you can find someone carrying small boulders back and forth (said boulder is about the size of their chest).

When using Bend Will on one of the All-Maker Stones, the person carrying the boulder ran over to see what was happening, while still carrying the boulder (to the left-hand side). The All-Maker Stone would then unleash a pulse of energy which destroys the dark constructs, making the stonework violently explode.

Clear your throat and bellow the Bend Will Shout directly at the stone. The rock arches glow red and then explode, snapping the Skaal villagers from their malaise. As the pieces of masonry fall away, something is summoned from Hermaeus Mora's realm!

(Skyrim Prima, page 592)

 

[Stocking Anarchy]

Using Bend Will on the All-Maker Stones will remove Miraak's evil influence over them and the people of Solstheim, and restore the natural order. These stones maintain the Oneness of the land. Even if this does not stop Miraak, it would delay his return.

Storn Crag-Strider

Storn Crag-Strider is the Elder shaman of the Skaal Village and the father of Frea. He lives in the Shaman's Hut, where he can be found at night. Storn is met when returning to the village with Frea. The Dragonborn tells him of the vision at the Temple of Miraak. Storn's fears had come to pass...

elderscrolls.fandom.com

Dovahkiin: What happened when I Shouted at the Wind Stone?
Storn Crag-Strider: The power of the Stone had been corrupted. It was the source of the influence that had taken control of the Skaal. Your Shout broke whatever evil will controlled the Stone, and restored its true nature as a conduit of the All-Maker's gifts. Freeing the other Stones will diminish whatever dark influence is spreading across Solstheim.
Dovahkiin: Other Stones?
Storn Crag-Strider: Yes. There are six sacred Stones – Wind, Water, Earth, Beast, Sun, and Tree. Through them the Oneness of the land is maintained. Frea saw that the Tree Stone now stands imprisoned in Miraak's new temple. I doubt you can free it until his power is broken. But you may be able to cleanse the other Stones. Even if this does not stop Miraak, it surely will delay his return.

Upon Miraak's death, Frea feels his dark influence has finally lifted from Solstheim.

Skyrim:Frea - The Unofficial Elder Scrolls Pages (UESP)

Frea: I can feel it. The Tree Stone is free again. The Oneness of the land is restored. Does that mean... is it over? Is Miraak defeated?

 

[Stocking Anarchy]

The All-Maker Stones are described as being the size of frost giants (the All-Maker Stones are at least twice as tall as the giants and Frost Giants we see in Skyrim; closer to how big they are in ESO).

If you head west and southwest along the main thoroughfare and around to a promontory overlooking the town, you can see some villagers hard at work erecting a strange monument around an odd glowing sacred stone the size of a frost giant.

(From the Skyrim Prima, page 587)

 

[Stocking Anarchy]

The All-Maker Stones that Miraak are corrupting are the same All-Maker Stones were once used in rituals during the time of the Bloodmoon.

Once used in the rituals during the time of the Bloodmoon, this is one of the All-Maker Stones sacred to the Skaal. Currently, it's power is being siphoned by Miraak and stone arches constructed by four enthralled sailors who were only supposed to take a short shore leave on Solstheim.

These All-Maker Stones are said to be gifts from the All-Maker.

Bloodmoon:Korst Wind-Eye - The Unofficial Elder Scrolls Pages (UESP)

en.uesp.net

Korst Wind-Eye: Heart-Fang wishes for you to do this, does he? Then I will assist you. There is a ritual that must be completed. On Solstheim, you will find six Standing Stones, each representing one of the six gifts of the All-Maker. At each of these Stones, a ritual must be completed. Once the Ritual of the Gifts is complete, the Oneness should be restored.

The Skaal believe all things to be in balance, and it's from this balance, this Oneness, that the Skaal draw their power. When this balance is upset, the power of the Skaal is lessened.

Korst Wind-Eye: There is a careful balance that lies in all things of this world. The animals, the trees, even the rocks and the winds. It is a harmony that the Skaal draw power from, by the grace of the All-Maker, He who gave us these gifts. When this balance is upset, our power is lessened.

When you have completed the ritual, Korst Wind-Eye can feel the balance has been restored.

Korst Wind-Eye: I can tell that the Ritual is completed. The Oneness once again flows through the land. Can you hear it in the trees? Do you feel the humming of the living land? It is a good thing you have done here, [Nerevarine].

These stone are the Beast Stone, the Earth Stone, the Wind Stone, the Sun Stone, the Water Stone and the Tree Stone.

 

[Stocking Anarchy]

Miraaks takeover of Solstheim wasn't his first or only attempt to escape Apocrypha, and during the 2nd Era he made another attempt. He is refered to as the First Servant, and considered a myth even among other ciphers, spinning plots and gathering power.

Online:Cipher Agrushna - The Unofficial Elder Scrolls Pages (UESP)

en.uesp.net

Cipher Agrushna: I think I might wait a while before going inside. I don't know how long it will take the Daedra and Hushed of Quires Wind to recover from the madness caused by those corrupted scrolls. Or at least calm down.
Vestige: Cipher Sabinius had instructions from someone called the First Servant.
Cipher Agrusha: The First Servant? I thought he was a myth. One of those stories of Apocrypha ciphers sometimes tell each other. But if he's real, his ambitions might lead him to seek out a disaffected cipher in Quires Wind.
Such as Sabinius.
Vestige: So who or what is the First Servant?
Cipher Agrushna: A mortal who lived in the days when Dragons were worshiped as gods, or so it's said. Hermaeus Mora opened Apocrypha to the First Servant, and he's been here ever since. Spinning plots and gathering power. Sabinius must have fallen into his web.
Vestige: What do we do about the First Servant?
Cipher Agrushna: Nothing. By tampering with Quires Wind, the First Servant set himself against the Great Eye. If Hermaeus Mora still has a purpose for the First Servant, he'll spare him. If not, he'll destroy him.
It's out of our hands.

In this attempt, he has had corrupted scrolls placed into Quires Wind (a scriptorium where secrets are bound into tomes) by Cipher Sabinius, which drives many there to madness, both mortal and daedra alike.

Cipher Agrushna: Beware, stranger! Madness stalks Quires Wind. Most of my fellow ciphers are lost—the Hush has taken them. And the Daedra of the Wind have turned on those few of us who kept our minds.
They killed mortals who have worked here for decades!
Vestige: What is this place?
Cipher Agrushna: Quires Wind is a scriptorium. Here the Great Eye's Daedra bind secrets into tomes. Ciphers like me help with this sacred task, preparing materials. Ink, blank pages, bindings. But the new scrolls Cipher Sabinius brought to the Wind are corrupt!
Vestige: Corrupt? How?
Cipher Agrushna: The scrolls give off a maddening aura. Sabinius left several hidden in the Wind. We need to destroy them, and make sure Sabinius has no more.
The Hush will take me if I go back. But an outsider like you should be able to resist. Can you help me?
Vestige: I'll destroy the corrupted scrolls and find Cipher Sabinius.
Cipher Agrushna: You'll find the corrupted scrolls hidden within Quires Wind. Sabinius is in there too. We can't leave him with any scrolls, blank or corrupt.
And watch out for Cipher Gelon. He's a clever alchemist, but I saw the Hush take him. He's dangerous.

Something strange is going on in the scriptorium of Quires Wind. Hermaeus Mora's servants, mortal and Daedra alike, have been corrupted by some outside influence. I agreed to investigate Quires Wind and deal with the source of corruption.

We finally have the blurb for the box for Betrayal of the Second Era!

The Elder Scrolls: Betrayal of the Second Era by Chip Theory Games - April Update: Pre-production Copies Have Gone to Print!

A HUGE moment for the campaign approaches!

gamefound.com

Tamriel is in turmoil! As the continent is engulfed by the flames of war, a mysterious figure has decided she knows the true solution to the chaos. To impose her will, she would fundamentally alter the nature of reality, heedless of the consequences. Until now, she has been able to accomplish her objectives behind closed doors, but a daring group of adventurers has learned of her machinations and is working to defeat her before she can perpetrate the betrayal of the Second Era.

Umbriel's appearance causes waves and storms to affect the seas, being the end of one poor vessel and the souls within. The effects are compared with a tsunami, but it's something different as they're in deep water (also, the natural disasters that plagued Summerset during the Oblivion Crisis are referenced).

When Iffech felt the sea shudder, he knew. The wind had already fallen like a dead thing from the sky, gasping as it succumbed upon the iron swells, breathing its last to his mariner's ears. The sky always knew first; the sea was slow—dreadful slow—to come around.
The sea shook again—or, rather, seemed to drag beneath their keel. Up in the crow's nest Keem screamed as he was tossed out like a kitten. Iffech watched him twist and almost impossibly catch the rigging with those Cathay Raht claws of his.
"Stendarr!" Grayne swore, in her South Niben twang. "What was that? A tsunami?" Her feeble human gaze searched out through the dusk.
"No," Iffech murmured. "I was off the Summerset Isles when the sea tried to swallow them, and I felt one of those pass under us. And another, when I was younger, off the coast of Morrowind. In deep water you don't feel much. This is deep water."

Umbriel's appearance is first thought of as being a thunderhead/cumulonimbus, and is accompanied by a clap like lightning, but 40 times louder, which snaps the mast off the boat.

And then he saw it, in the south, a sudden blackness, a crackle of green lightning, and then a form like a tall thunderhead billowed into being.
"Hold on!" he shouted.
And now came a clap like thunder but forty times louder, and a new fist of wind that snapped the mainmast, taking poor Keem to the death he had nearly seen. Then all was still again, except for the roaring in his damaged ears.

The energy Umbriel gives off is similar to that of an Oblivion Gate (even though Martin has shut all gates to Oblivion; at least all non-pact breaking ones).

"I saw an Oblivion gate open once," she said. "When my father worked in Leyawiin. I saw things—it feels a little like that. But Martin's sacrifice—they say it can't happen again. And it doesn't look like a gate."

Another shockwave is unleashed (with something 'unbelievably foul' being carried on it), and the ship is destroyed.

It wasn't shaped like a thunderhead, Iffech realized. More like a fat cone, point down.
Another wind was starting up, and on it something unbelievably foul.
"It doesn't matter what it is," he said. "Not to us."
And a few instants later it didn't.

During the Made Up Word Round Up (a discussion on the Bethesda Forums), Numidium is refered to as having the ability to alter the laws of nature and mathematics, to the point that time 'before' and 'after' the Dragon Break can be considered two different universes. This could also explain why even the nature of the cosmos is described differently in different installments.

Brennus casts a spell that instantly disintegrates at least three wormies (undead controlled by daedra from Umbriel), possibly more. Said spell bursts up from the ground, so it's possible it's some form of lava (from Lord of Souls).

How many of ’em do you think there are?” Brennus asked as various implements began thudding into the door. “Fifteen, I guess.”
“You can’t count any higher than that,” he said. “It could be thirty.”
“Could be,” she said. “Doesn’t really matter, does it? They can only get at us one or two at a time.”
“Oh, well, I can’t dispute that logic,” he said.
There was a splintering sound, and daylight and the edge of an ax appeared. Mazgar rested Sister, point down, and took long, deep breaths, watching as the door disintegrated and the leering, rotting faces of the enemy appeared.
“Stand back a bit,” Brennus said as the first of them came through.
“You save your strength,” she snapped, but it was too late. A sheet of white fire erupted from the earth a few feet on the other side of the door. She saw at least three of the things more or less disintegrated immediately. Half of one fell into the other side of the house, but it didn’t move again.
She glared at Brennus, but he was sitting against the wall, eyes closed, face pallid.
“All yours now,” he said.
So she waited until the eldritch flame began to subside and then placed herself in the frame of the door so Sister could swing freely outside.
But when the spell dissipated, she saw there weren’t any wormies left standing. She found herself regarding instead about twenty men in heavy armor, most astride barded horses. Two were dismounted, making certain the wormies weren’t going to get up. When they saw her, one of them doffed his helmet, revealing a dark Dunmer face.

 

[Stocking Anarchy]

From Lord of Souls, when Attrebus and Sul are on Solstheim, a supernaturally cold mist descends from the mountains and covers the valley. Fruth assumes it's a frost giant, however...

Beyond the rise, a valley spread, and beyond them mountains whose peaks vanished into the oppressively low clouds. “Ensleth Valley,” the guide said, lifting the point of his red beard. “Good hunting here. Elk, deer, muskrey.”
“Very good,” Attrebus said, scribbling that in his book. “And those mountains?”
“Moesring Mountains,” Fruth said. “We don’t go there much.”
“What makes this valley so good for game?” Attrebus asked. “It looks just like the last one.”
“Salt,” Fruth replied. “Big salt lick along where the stream comes out. Only one on this side of the mountains. You’ll want to
see that.”
“Sure,” Attrebus said. “I suppose so.”
As they were about halfway down the slope, Fruth’s head jerked up sharply toward the mountains. Attrebus followed his gaze and saw what appeared to be a white cloud rolling down it toward them at impossible speed. Fruth’s gaze darted around, but then he gestured back upslope.
“Hurry!” he shouted.
But they had only gone a few steps before it hit them.
Attrebus had heard of avalanches, huge slides of snow coming down mountains, destroying everything in their paths. He assumed that’s what this was, and braced for it, yet what hit him wasn’t a wall of snow, but an unbelievably cold mist. Snow came with it, but whirling in the air, biting at his face. He couldn’t see anything. He stumbled, then struck his foot against something and went tumbling down the slope, flailing wildly, thankful at least for the layers of fur and leather the servants of Sathil House had given him to wear. Even so, he felt the temperature dropping impossibly fast.
Someone caught hold of him and drew him along with terriblc strength, and after what seemed a long time, pulled him down into what felt like a stony grotto.
“Keep close,” a voice said—he recognized it as Fruth’s by the accent. A moment later something warm and faintly luminous appeared between them. It looked something like 􏰊ame caught in a ball of glass, and after a few moments it seemed to push the worst of the cold away.
“What was that?” he asked.
“It comes down like that sometimes,” Fruth said. “Never seen it come so fast, though. Unnatural, probably Frost Giant.” “Frost Giant?”
“Yah. Unpredictable, this new one, and very strong.”
“What about Ozul?” he asked, using Sul’s false name. “And the others?”
“We’ll find out when this is over,” Fruth said. “We go out now, we freeze. Freeze anyway, if this stays too long.”

Sul managed to scramble far enough up the hill that the wave of freezing air went below him, but it enveloped Attrebus and Fruth, blotting them from view. He started down but was arrested by an eldritch tingle that told him—as his common sense should have—that the event wasn’t natural. He spun, fingers clenching on the hilt of his sword, an invocation already begun in the back of his throat

Sul is soon confronted by Sathil, who claims it was from a frost giant too. However, Sul finds this suspicious...

“Yes, I’m sorry we didn’t arrive in time,” Sathil said absently. “The new Frost Giant is somewhat feckless. He usually doesn’t haunt this side of the Moesrings until midwinter.”
“Frost Giant,” Sul replied dubiously.

Sul believe's it's Sathil (not a frost giant) who changed the weather in the valley. This is noted as being impressive, and if Sathil is power enough manipulate the weather itself then he can do all sorts of things to them when they're being held prisoner.

“What then?” Attrebus asked. “I have a feeling she’s not just going to let us starve to death now.” He brightened. “If she sends guards, they’ll have to open the gate to get to us.”
“If it were me, I would send down clouds of noxious fumes,” Sul said, “or seal the passageway and let us su􏰊ocate. Or pour down barrels of oil and set them aflame, if there is no one here with such arcane knowledge.”
“If her father made that weather at the valley, I’m sure he can do something pretty nasty to us if we’re trapped down here.”
“My thought, too,” Sul agreed.

 

[Stocking Anarchy]

From Lord of Souls, Elhul Sathil with Umbra has turned into a skeletal monster.

In the ruddy light, Elhul Sathil was hideously revealed.
He had skin but no flesh, and the skin fit him so tightly his bones were all plainly revealed.

Despite this sickly form, Elhul possesses immense strength granted by the dark sword. Elhul moves at 'unbelievable speeds.'

“I told you—” Sul began, but Elhul was suddenly bouncing toward Attrebus with unbelievable speed. There was no attempt at technique; Umbra chopped down toward him like a cleaver. He met the blade with Flashing’s flat edge.

Elhul's blows bring Attrebus to his knees, and despite Elhul looking as if he weighed only 60 pounds (over 27kg), he feels as if he's made of cast iron.

The blow drove him to his knees and sent arrows of pain into his shoulder. Gasping, he flung himself forward in an attempt to tackle the apparition—but although Elhul looked as if he only weighed sixty pounds, he felt as if he were made of cast iron.
Elhul boxed his ears, and Attrebus stumbled back, his head ringing exactly like a bell. Elhul came after him. Lightning crackled about him but he didn’t miss a stride.

Attrebus tries to stab Elhul, but the sword doesn't even break his skin.

Elhul lifted the black sword to strike again, and Attrebus drove Flashing into his solar plexus. Or tried to; the point didn’t break the withered black skin. Still, the impact sent Elhul back a step so that his swing smacked into the cave floor rather than Attrebus’s skull. Attrebus cut hard at his foe’s head; it felt like hitting a statue. Elhul shook it of as Attrebus backed away. Elhul stopped screaming, and then spoke.

Elhul is destroyed by a powerful corrosive spell from Sul, which melts the stone itself. Sul says he was starting to thing nothing would work against him.

But Elhul stopped in mid-stride, his mouth open as if to scream again, though no sound issued. Instead a smoking green fluid vomited out. He clapped his free hand to his head as the same viscous stuff jetted from his eyes and ears. Holes began to burst in his abdomen, and he crumpled, breaking into pieces. Where the vitriol touched stone, it too began to dissolve.
“Get back,” Sul said. “Don’t touch it.”
“I wasn’t considering that, believe it or not,” Attrebus said, trying to keep his breakfast down. “That was—” But he didn’t have a word strong enough for whatever magic Sul had just used.
“It worked,” Sul replied. “I was starting to think nothing would.”

The sword of Umbra itself is unscathed by this.

Attrebus looked back at the remains—which now consisted of a fuming green puddle—and the sword, which seemed untouched.

It takes 20 minutes for the floor to stop smouldering.

As it turned out, they didn’t have to hunt hard or long; in a moldering pile of clothes and bedding they found a sheath. After about twenty minutes, when the floor finally stopped smoking, Sul pushed the scabbard onto Umbra.

 

[Stocking Anarchy]

From Lord of Souls, after Umbriel stole a large portion of Viles power, what remains of his Realm (the Fields of Regret) are twisted and unhealthy, with there being unsettling patches that seem more to be 'stains on the sky' than clouds.

Attrebus found himself on his back, staring up at what appeared at first to be a few cottony clouds in a perfectly blue sky. But as he garnered his strength to rise, he noted odd unsettling patches, greenish-gray streaks that didn’t appear to be clouds but were more like stains on the sky itself.

Similarly, the woodlands are twisted and sickly (and even melted looking), with scents of decay beneath the smell of the wildflowers. Curiously, this realm is compared to the works of the painter Lythandas of Dar-Ei (whom we meet in Oblivion; there are theories that the Brush of Truthpaint is actually an artifact of Clavicus Vile rather than Dibella).

They had landed in a field of white clover—a woodland meadow that might have come right out of the paintings of Lythandas of Dar-Ei. But like the sky, a close look revealed withered, twisted foliage and odd melted-looking places that his eyes couldn’t focus on. Beneath the perfume of wildflowers, the breeze carried a scent of profound decay, like a wound gone to gangrene.

As they pass through this realm, they see a creature which changes shape several times, from a bird to a butterfly to a winged caterpillar.

Something fluttered by in the trees, which he at first perceived to be a bird, then a butterfly the size of a hawk, and finally a caterpillar with wings.

With most of his powers missing, Clavicus Vile can only maintain his realm (or at least this world in particular) for around a mile in radius, beyond which it all becomes a shimmering chaos.

They wound along a spiral trail up a hill, where they found a table large enough to seat thirty or so, with whimsically slim legs that terminated in hooves. Now and then one of the hooves would lift and stamp, rattling the empty plates and cups on the table. Beyond the hill, the colors of the world seemed to melt and flow before the sky gave way completely to shimmering chaos. From this height, Attrebus could see that the trees and grass only extended a mile or so in any direction before similarly dissolving at the edges.

While Vile says he's just as strong as ever, Barbas disagrees with this conclusion. With less of his power to work with, Viile has it more concentrated than before.

“Don’t think I’m weak,” Vile said. “Everyone who comes here now thinks I’m weak, just because a wee bit of my stuff has been stolen. The trick is, if you’ve got less to work with, you just don’t spread it so thin. My realm may be a little smaller than in happier times, but in it I’m just as strong as I ever was.”
“Well,” the dog said, “I wouldn’t go that far.”
“Hush, Barbas, before I feed you to my hounds.”
“Which would be me, sir,” the dog said.

Umbra is actually an aspect of Clavicus Vile, and Vile considers this entity to be no different from himself.

“First of all,” Vile said, “let’s not go calling anyone ‘Umbra.’ There is no Umbra. This—thing—that suffers from the delusion that it is its own—person—is actually nothing of the kind, do you understand? No more than a stone rolling down a hill is capable of real self-locomotion.
