The Library

The Library, also known as Es's room, is where the entirety of Alter Ego takes place. Little is known about this strange place, though it is filled with books about psychology.

Appearance
The Library could be considered bleak in many ways, as it is filled only with books. The only thing inside that is not a book is a desk, upon which sits a broken mirror, a birdcage, and several envelopes.

Alternate Appearances
After receiving the Super-Ego ending, where Es gives into Ego Rex and disappears, Ego Rex's face can be seen lining the shelves, with no books to be seen.

After receiving the ID ending, where Es shuns out the world and goes mad, the books have been knocked down from their shelves and scattered around the room.
