A city of mind flayers that exists in Toril's Astral Plane. Can be accessed from anywhere strange distortions can conceivably be found, in places where the world has already altered - it is entirely possible to stumble from one fourth wall-only location into this one - or through teleportation and other transportation magics.

The hivemind is a vertical maze of winding, strangely organic corridors. There are, quite often, guardrails instead of walls, so that visitors and inhabitants can gaze out into the limitless star-sea of the Astral Plane.

There are many rooms, but the biggest, most elaborate room contains a large pool in which a giant brain pulses and floats, surrounded by Malamar. Inkay swim in the pool with the brain, quite happy to be there. While communing with the elder brain is not possible, walking into this room will grant the feeling of an awe-inspiring, but still comfortable, presence.

Pokemon that can be found here: Practically any psychic type you can think of, though the most common ones have something extraterrestrial implied about their origins (Elgyem line, Solrock and Lunatone, Starmie, Minior, etc etc). Anything that has implications of a space-themed origin can also be found here (like the clefairy line) .There are also an awful lot of Inkay and Malamar around.
