The Inferno

 is the infinite series of dungeon rooms that lie deep below Hildebrant's Cellar. Various Lore Store items can be unlocked by descending through the cellar and reaching this area.

Description
Once a character has reached and defeated all enenemies on floor 9 of Hildebrant's cellar, they will then descend down into the Inferno. This series of dungeon floors is, to date, infinite. Players face a variety of enemies and the usual dungeon traps, and will occasionally find treasure chests. Goblin merchants will also sometimes appear and are the only way to restock on supplies using gold during a cellar dive; otherwise players are forced to rely on the random loot drops they can find while exploring the dungeon.

There is currently no reward for descending beyond floor 9.
