Rift of Niltak

From PathfinderWiki

The Rift of Niltak is a mist-shrouded canyon found in the Red Mountains of north-eastern Varisia. No one knows what the origins of the rift are, but all agree that it is filled with all manner of strange flora and fauna. Gigantic insects and centipede horrors can be seen crawling over plants found in no other place on Golarion, and the echoes of shrieking bat-like creatures reverberate off the glen's walls.

An accurate description of the rift has not come to light, as those who enter either never return, go insane, or commit suicide shortly after emerging from it.12
