Au Tsum was first seen in the western edge of Dusk Valley, where he lay sleeping. Lungoray awakened him by splashing a potion made from glow worms over him. The potion allowed Eywa to influence his actions, and he rampaged north, straight through the RDA base in the Hammerhead Graveyard.
- Au Tsum's name may be a reference to A' Tuin, the great turtle on which the Discworld is supported in the eponymous franchise.
