The southwest area of Nightmare Caves features a maze of gates and levers with the [[Lost Penguins]] quest. This area is filled with non-elite level 90 [[Forthragarian Engineer]], [[Hippogryph]], and [[Hexapus]] and is a good place to farm level 90 gear solo, as well as skill books. This area also contains a barter for some lategame brewery items including rum. To acquire the rum, labels must be picked up from spawns in the Penguin Maze, and the bottle must be acquired from [[Ship In A Bottle]].
