An Evulsor is a biomachine which pump liquids from subterranean liquid gas veins in Ja’luhhor’Alotha. The liquids are pumped into a gelatinous storage sac attached to the walls near the Evulsor. Which then drains its contents into a nearby valve, which then funnels the liquids into nearby pipe networks which allows them to flow to their necessary destination.

Evulsors almost always pump liquid oxygen into their storage sacs for use in the Aesoteric’s growing amount of electrical generators. They are almost always inside the enclosed labyrinths in Ja’luhhor’Alotha. While the processes of an Evulsor may seem automatic, they require subterranean operators to maintain their proper function. These operators are usually unfortunate organisms, who have been grafted to the walls of their decrepit controlrooms.
