The Yavian Inferno (also just the Inferno) was the fiery subterranean world beneath the surface of the planet Yavia. The Inferno was dominated by the Moloch tribe, which used Bone, Coal, Sulphur and Magma instead of Wood, Stone, Putty and Goo. The Inferno had its own unique native monsters, including Spurtz, Balthazar, King Wormzer and Korath.
