Ols are shape-shifting formless horrors created by the Shadow Lord to spy and do its evil bidding. When attacking, they reveal their true forms.
The Deltora Book of Monsters said:The Dread Gnome Sha-Ban told me of these white, formless creatures that could take the shape of any living thing - human, animal, or even insect. When attacking, she said, Ols emerge from their disguise, rising like ghastly, flickering white flames with holes for eyes, gaping, toothless mouths, and strangling hands.
There are three levels of Ol; Grade One Ols, Grade Two Ols and Grade Three Ols, which each level up getting better at disguising itself, smarter and more powerful. Ols can take the shape of any living thing. Though they do not eat or drink, Grade Two Ols can pretend to do so, and even create body heat to further their disguise. Every Ol has the mark of the Shadow Lord somewhere on its body (though Grade Two Ols and up are much more clever with where they hide their marks), and Grade Two Ols can only hold their form for three days, after which their shape begins to change and waver for a few seconds (this is called the tremor).The Maze of the Best said:“What are these Ols?” Jasmine demanded, as she passed Dain a mug of tea for himself.
“Shape-changers from the Shadowlands,” Dain said, stirring a spoonful of honey into his own cup. “The Shadow Lord uses them to do his evil work. Perhaps I should not be surprised that you have not heard of them before. They are more common here, in the west, than in the east, where you come from.”
Grade One Ols always travel in pairs (though Grade Two Ols may not have this limitation, and Grade Three Ols defiantely don't).The Maze of the Beast said:“They are everywhere,” Dain said, pulling his blanket more tightly around him. “They can take the shape of any living thing. They do not eat or drink, but Grade Twos can pretend to do so, just as they can create body heat to disguise what they are. In its natural state, every Ol has the mark of the Shadow Lord at its core, and whatever shape it takes, the mark will be somewhere on its body, in some form.
“The twins — the Ols we killed — each had a mark on the left cheekbone,” said Lief. “Was that —?”
Dain nodded. “But do not expect that it will always be so easy,” he warned. “Grade Two Ols are far more expert. They never have the mark in plain view.”
“You are saying, then,” Barda put in, frowning, “that recognizing a Grade Two Ol is just a matter of luck?”
Dain smiled slightly. “There is a way of testing them,” he said. “They cannot hold one shape for longer than three full days. If you observe a Grade Two Ol, and never let it out of your sight, there will come a moment when it loses control and its shape begins to change and waver. We call this moment the Tremor. It does not last long. In seconds the Ol has regained control. But by that time, you know it for what it is.”
The Shadow Lord sent hundreds of Ols into Deltora to spy and kill.The Maze of the Beast said:Dain swallowed the last of his tea and stood up awkwardly, protecting his injured arm. “I will leave you in peace. Be on the watch for Ols. Grade Ones, like the two we have just dispatched, always travel in pairs. The others — well, you will probably not recognize them, anyway. It is best to trust no one.”
To kill an Ol, one must pierce it through its heart, which is located on the right hand side.The Deltora Book of Monsters said:She said that Ols had been created by the Shadow Lord and sent into Deltora in the hundreds to spy and kill.
Ols posses incredible strength, and their touch is so cold as to be crippling.The Maze of the Beast said:“Through the heart!” the injured boy shouted. “Stab it through the heart! Kill it outright or it will finish him!”
“It is stabbed through the heart already,” Jasmine shrieked. “It does not fall.”
Growling, the thing turned on her. With a cry she was swept aside by a rush of white that sent her sprawling.
“Now, Lief! Strike on the right side!” the boy screamed. “The heart is on the right side, not the left!”
An Ols touch can chill to the bone.The Deltora Book of Monsters said:If you suspect you are in the company of an Ol, slip away quietly. Do not try to stand and fight. Ols have enormous strength, and the dread chill of their touch is crippling. They can only be destroyed by being pierced through the heart, which is on the right side instead of the left.
An attack from even a Grade One Ol can leave bruises (seemingly from the sheer cold), as it did with Barda.The Maze of the Beast said:The boy nodded briefly, then limped to where Barda was lying and looked down at him. “Your friend needs warming,” he said. “He is wet, and Ol attacks chill to the bone.”
We also see this when Doom is attacked by a Grade Three Ol.The Maze of the Beast said:“Or,” Barda put in, “if your suspicions are correct, to be spied upon by the Ol at its leisure, or killed when you least expect it. Once those icy fingers are around your throat, you are helpless. You can take my word for it, Jasmine.” He touched his own bruised throat tenderly.
Regular weapons are useless against an Ol in its true form except if used to pierce through it's heart.Return to Del said:He clasped the Belt around his waist and threw himself down to the bottom of the pyramid, to where Doom lay. Doom was muttering, shuddering with cold. His lips were blue. Great red marks wound around his neck. There was a swelling bruise on his brow.
The cold of an Ol is said to freeze limbs, sting eyes and turn lips to ice. An Ol picks up Jasmine with one hand, while grabbing Lief's arm with the other (with it's grip being compared with 'frozen iron').The Maze of the Beast said:Gasping in horror, Jasmine and Lief both lunged forward, stabbing and tearing at the thing, trying to pull it away from Barda. The cold, wavering mass shrank and re-formed. The thing staggered, but its grip held.
“Through the heart!” the injured boy shouted. “Stab it through the heart! Kill it outright or it will finish him!”
“It is stabbed through the heart already,” Jasmine shrieked. “It does not fall.”
Growling, the thing turned on her. With a cry she was swept aside by a rush of white that sent her sprawling.
“Now, Lief! Strike on the right side!” the boy screamed. “The heart is on the right side, not the left!”
Beyond Grade One and Grade Two are Grade Three Ols, in whom the Shadow Lord is said to have perfected his evil art. They can turn into even inanimate objects, and can mimic a person so perfectly that not even Doom (who can sense the presence of Ols) can tell them for what they are.The Maze of the Beast said:The chill of the Ol came before it — a breathtaking cold that froze the limbs, stung the eyes, and turned the lips to ice. Gasping, staggering back, trying to shield Lief with her body, Jasmine swung her dagger at the white, grasping fingers. Half-stunned with cold, Kree dashed himself against the thing’s peaked head.
But nothing, nothing could stop it. The fingers of one hand snaked forward and caught Jasmine around the neck, lifting her from the ground. Almost carelessly, the other hand grasped Lief’s dagger arm in a grip of frozen iron. The dagger fell clattering to the deck.
The Maze of the Beast said:Jasmine lifted her chin stubbornly and turned again to Dain. “You have spoken of Grade One Ols, and Grade Twos. Are there other grades as well?”
Dain hesitated. “Doom says that there is another,” he said reluctantly at last. “He says there are Grade Three Ols. He says they are few, but in them the Shadow Lord has perfected his evil art. They can change their shape to whatever they wish — living or nonliving. They are so perfect, so completely controlled, that no one could tell them for what they are. Even Doom could not.”
“Then how does he know they exist at all?” Jasmine demanded.
Lief watched, fascinated, as Dain’s eyelids drooped, and he bit his lip. What was troubling him?
Jasmine saw the hesitation, too, and pounced. “Well?” she insisted.
Dain swallowed. “Doom says — he says he learned of them — in the Shadowlands,” he muttered.
At least one of the advisors for the royal family of Del, Prandine, and his successor Fallow, were Grade Three Ols.The Valley of the Lost said:And Doom claimed that there were Ols who could take the form of things that were not living — Grade 3 Ols, the perfection of the Shadow Lord’s evil art. If the tale was true, and such beings really existed, the very bush on which Kree perched, or the pebble at Lief’s feet, could be a secret enemy. At any moment a horrible transformation could begin. At any moment a white, flickering specter with the Shadow Lord’s mark in its core could rise and overwhelm them.
Nowhere was safe. Nothing could be trusted.
However, while Grade Three Ols are the most powerful of all the Ols, when in human form they are also the most vulnerable.Return to Del said:... where one dies, there is always another to take his place. The Master likes this face and form. He chose to repeat it in me ...
Lief had not known what that meant, when first he heard it. Now he knew only too well.
Fallow was an Ol, and perhaps — almost certainly — one of the Grade 3 Ols Doom had heard of in the Shadowlands. The triumph of the Shadow Lord’s evil art. An Ol so perfect, so controlled, that no one could tell it was not human. An Ol that could mimic nonliving things as well as living creatures. An Ol that was evil and powerful beyond anything Lief could imagine.
Prandine, King Endon’s chief advisor, had been one such being. Of that Lief was sure. Fallow, made in his image, had taken up the Shadow Lord’s work where Prandine had finished.
Dain reveals that he too is a Grade Three Ol, and took the form of his own dagger when he tricked everyone into thinking Ichabod had kidnapped him.Return to Del said:Lief turned restlessly. Queen Sharn had killed Prandine — tipped him from the palace tower window to crash to his death. Grade 3 Ols paid a price for their perfection, then. They could die as humans could.
Dain's grip is compared to 'icy steel,' and with a glance he makes it so that Lief's sword is too hot for him to hold.Return to Del said:His mouth twisted in scorn at the expressions on Lief’s face. “You fool! You never dreamed that Ichabod was acting under my orders. That he had not carried me away, but was running alone in the dark, babbling of Del! And when you found the dagger I had become, you did not suspect it for a moment — even though you knew that Grade 3 Ols could take any shape they wished. You put it in your own belt, as I knew you would, snivelling for my loss, little knowing that you were carrying me with you from that time on. I was watching your every move. Listening to your every plan. Waiting to see how best I could destroy the devil Steven and that accursed Belt. And when I knew enough — I left you, and came here to prepare ... this.”
Dain transforms back into his true form to avoid being stabbed in the heart by Doom, and the cold that's unleashed extinguishesReturn to Del said:His hand swung, striking Lief’s arm a tremendous blow, knocking the Belt into the fire. With a cry, Lief grabbed for it. But Dain had his wrist in a grip of icy steel. Dain’s eyes narrowed, and suddenly Lief’s sword was white-hot. It fell from his blistered hand and clattered, useless, down the steps of the platform.
These flames were part of a bonfire to burn Dain (whom even the Grey Guards don't realise is a Grade Three Ol), which was even oiled to make it burn more furiously.Return to Del said:With a cry, Doom leaped upon Dain, knocking him down, his sword plunging for the heart. But Dain twisted like a snake, his body dissolving, rising again in a column of sickly white. Icy mist coiled around him. He whirled around, his fingers reaching for Doom’s throat. Long, thin fingers, bringing with them the chill of death.
Lief staggered back, shuddering in a cold that was beyond imagining. The fire wavered, and went out.
Return to Del said:Torches were blazing everywhere. Ten Grey Guards were working in the middle of the square. They were heaving huge blocks of stone into place to make a stepped pyramid with a flat top. Through the center of the pyramid rose a tall pole, towering high and held in place by the blocks that surrounded it.

Return to Del said:“Awake at last, your majesty?” Bak 1 was sneering. “That’s good.” He beckoned, and his fellows began toiling up towards him, their arms full of dead branches. As they dumped the wood around Dain’s feet, piling it high, Bak 6 sprinkled it with oil.
When Dain is destroyed, all the other Ols in the square are left in a confused & aimless state.Return to Del said:In seconds he had reached the platform. Alone he leaped up to the top, sliced through the ropes that bound Dain, pulled the limp body from the flames.
There at least a hundred of Ols in the square.Return to Del said:Lief looked up wildly. Jasmine and Barda were racing towards him. The Ols in the square were not coming after them. They were wavering, aimlessly clustering together, as though they were confused. It was as though the source of their power had been struck a blow by the destruction of the great one among them.
But already some of them were starting to recover. And the red clouds were tumbling, boiling, as they raced towards the city.
Return to Del said:Shouts and groans rang from the square as Jasmine and Barda, torches blazing, held back a hundred crawling Ols, and the prisoners were dragged away. The sky was a mass of scarlet cloud.
Return to Del said:Rats poured from the little yard where the caravan stood. As they ran they shimmered and paled, rising into wavering white flames with coals for eyes and gaping, toothless mouths. And in the core of every one was the Shadow Lord’s mark.
