The basic enemies found here are very devastating, as all of them can do 4th wall and Alarm, both 1-hit-killing moves.This area's name may be a shortened version of 'PurpleGeist Lair'.In the original 1.20 update, it was still possible to use the jump buttons in Geist Lair.Scott described Geist Lair in a Steam post as 'a one way trip. The jump buttons do not work in Geist Lair, similar to &*_TWRE.It will not drain if the attack Bubble Breath is used.However, when in battle, the health is shown to be drained, mostly due to toxic air.Though said it is filled with toxic air, the area is shown to not have any.If the player pulls up the map with Tab while in Geist Lair, it is revealed that it is located to the east of the world map.PurpleGeist appears at the northernmost area of the map, waiting to trigger the final battle.
As said by Fredbear, the place is filled with toxic air, which drains the character's HP in battles. Like Deep-Metal Mine and Mysterious Mine, most of the area is covered in darkness. The place is made out of several rocks and lit torches.
