The Window

Located in city ruins of Othelin on Strata 17, The Window is a functioning Glyph Lore artifact/device. Presumably an upscale version of the Glyph Transportation System in Bastion, it's theorized that it was created as a way to both scry and transport to other places on Home, keeping an eye on the after-effects of the Miasma.

An AXE Team with Alice and Co. found The Window (details in the story We Came Upon A Window) and was able to bring it to operational capacity (something only a Lunarian could have done).
