The far eastern part of Hallownest, constantly snowing with white ash from a massive deceased Wyrm. Bodies from the Colosseum of Fools fall from above into the acid pits below. In the far southeastern part of the area is a deep pit that leads to the largest Geo deposit in the game.

Giant Geo Deposit
Near the Nailmaster's Hut is the entrance to a downward passage that goes far beyond the Kingdom's Edge. The chasm crosses three environments that respectively take traits from the Kingdom's Edge, the Forgotten Crossroads and then finally Ancient Basin, but is only occupied by three lone Hoppers. At the bottom is the largest Geo deposit to be found in Hallownest. Hidden midway in the Ancient Basin area is a small room overgrown with mushrooms and hinted at by spores. It contains a single lore tablet which hints at the Passing of the Age quest.
