From publisher blurb: Burning Engines are a rare and dangerous protector of dwarven catacombs. Mostali technicians bind spirits of fire within lifeless hulks of metal, creating immortal guardians capable of roasting pesky adventurers. This RuneQuest supplement describes three "species" of burning engine, new sorcery spells for Lhankor Mhy adventurers to command a burning engine of their own, and an adventure seed which pits players against a fallen star driven mad by The Dwarf with the pain of its binding.
