Rage End Crater
From Dreams of Hope
Formerly Mt. Fearg at the heart of the Dead Plateau; in 250 AC it collapsed (totally unrelated to any adventures Enigma may have participated in there) and didn't just collapse--it inverted, forming the roughly 3000-ft deep Rage End Crater. There are less-deep shelves around portions of it, but the depths are uncharted and full of nasty things.
After the destruction of the Red Fang and Loran Hae by the Oblivion Gate, the area has become, if anything, even more nasty. Travel guides mark this as "avoid at all costs".
