Little is known about the Hetwans' life before Everworld, but like all alien species (those not from human mythology), they were brought there from another world (not "our" world) by their particular deity, the dread-god Ka Anor. They then began to conquer everything they came across, while collecting gods for their deity to consume. The Hetwan kingdom in Everworld alternates between perfectly hemispherical hills and gullies, giving a scooped-out appearance. The alien trees make strange musical sounds. The Hetwan capital, where Ka Anor resides, is a massive tower (dubbed "Junkie Dream Mountain" for its needle-like appearance) in the middle of a lava and glass filled crater. The only transportation across this gulf is by means of the "Red Wings", giant insects that can carry passengers.
