Manah dies, the Sky Fortress begins to collapse and fall from the sky

What this tells us is that Manah's magic is what keeps the Sky Fortress aloft and together and her death means its all kinds of fucked

After all, its only after she dies that we're informed that the Fortress is now both "helmless" and lacking someone to control it thus acting as the cause of it falling from the sky and collapsing under its own weight. Manah was the helm of the fortress and she controlled it through her magic.

So let's get this convoluted mess going~

Angelus Length = 135 pixels
Angelus Wingspan = 184 pixrls
Angelus Length/Angelus Wingspan = 1.363

Angelus Length = 25.4 meters (official size)
Angelus Wingspan = 34.62 meters

Angelus Wingspan = 441 pixels
Pillar Height = 815 pixels
Pillar Height/Angelus Wingspan = 1.848

Pillar Height = 63.978 meters

Pillar Height = 65 pixels
Distance = 422 pixels
Distance/Pillar Height = 6.492

Distance = 415.345 meters

A perfect world would have given me an entire render ripped straight from the game of the damn thing to use, but I'll have to settle for the next best thing with concept art~

Distance = 46 pixels
Sky Fortress Diameter 1 = 373 pixels
Sky Fortress Diameter 2 = 496 pixels
Sky Fortress Diameter 1/Distance = 8.109
Sky Fortress Diameter 2/Distance = 10.783

Sky Fortress Diameter 1 = 3,368.033 meters
Sky Fortress Diameter 2 = 4,478.665 meters

Sky Fortress Diameter 1 = 209 pixels
Sky Fortress Height = 125 pixels
Sky Fortress Height/Sky Fortress Diameter = 0.598

Sky Fortress Height = 2,014.084 meters

Half Hollow Ellipsoid Volume = 0.5((4/3)PIr1r2r3) (Watch for yourself here why I figure it's only half hollow)

r1 = Sky Fortress Diameter 1/2
r2 = Sky Fortress Diameter 2/2
r3 = Sky Fortress Height = 3/2

Sky Fortress Volume = 7,949,702,900.659 m^3
Rock Density = 2,700 kg/m^3 (the graphics texture looks rock like anyway)
Sky Fortress Mass = 21,464,197,831,779.3 kilograms

Now, can't really scale the height in the sky due to the sheer lack of detail Cavia gave us to work with graphically.

Can use the fact Angelus has trouble flying to its height in the sky without an unnatural updrafty aircurrent Inuart seems to call after he flees from your ass as something of a ballpark however.

Namely, let's compare the ceiling Angelus can fly as being like the highest recorded bird flight height which is some 37,000 feet or otherwise known as...

Height of Fortress = 11,277.6 meters

Potential Energy = MGH

M = Sky Fortress Mass
G = 9.8 m/s^2
H = Height of Fortress

Manah's Total Magical Power = 2,372,233,447,183,207,000 joules or 566.977 megatons

As for the general fact the structure caves in under its own weight due to Manah no longer keeping it from caving in?

Let's use fragmentation at 8 j/cc as something of a placeholder for the entire structure's minimum threshold durability *shrugs*

Sky Fortress Volume = 7,949,702,900.659 m^3

Energy Manah expends to keep the Sky Fortress from Collapsing = 63,597,623,205,272,000 joules or 15.2 megatons

Final Tally

Manah's Total Magical Power = 566.977 megatons

Energy Manah expends to keep the Sky Fortress from Collapsing = 15.2 megatons

I do high school physics for stupid shit because I find it fun for some ridiculous reason.

I'm neither a physicist or engineer. I study psychology.

Before taking me at my word, think for yourself and don't just appeal to the shit I'm posting without evaluating it yourself. That should go without saying. I'm not an expert, do not treat me like one.
