Well, I just read some people arguing about how the towers were "Methods of escape" from Mundus". I had always been under the impression that the towers were simply methods of the elves dealing with their sundered state rather than straight-up escape routes. From what I know these are the towers and their purposes, anyone care to correct me on my misunderstanding if this?

Walk-Brass - The Dwemer's method of Ascension by Collaboration, the Numidium.

Crystal-Like-Law - Has something to do with "Dracochrysalis", which I'm not too clear on.

Snow-Throat - I tend to lean towered the idea that the Snow-Throat is the throat of the world, and it was made a tower in the ancient heroes' banishment of Alduin.

Orichalc - Unknown, though it was on Yokuda.

Green-Sap - Falinesti, though still unsure in the purpose.

White-Gold - Harnesses creatia in order to mold the world to the wishes of the Ayleids.

Direnni - Auri-El's spaceship in which the convention stabilized Mundus.

Red - The Red Mountain in which Lorkhan's heart was thrown after his death.

Khajiit & Lunar Lattice - Debatable on whether this is a tower or not. It also stabilizes Mundus, keeping Daedra and such out.

So, any clarity on the purpose of the towers?

Dracochrysalis = Dragon/Time + cocoon/transformation.

I think every Tower was created by elves, including Snow Throat.

White-Gold is special in that it forms the central point in a "wheel within a wheel" which grants it extra importance in the metaphysical aspects of Tamriel. Its stone was the Chim el-Adabal.

The Khajiit created a Tower of themselves to reach the Moons and Sugar, but I have no source to provide to you.
