Golems wait silently in dungeon corridors, ready to apprehend unwary adventurers who dare defile their former master's sanctum. Shield guardians follow their owners faithfully, interposing themselves between the holder of their amulet and anything that would bring him harm. Homunculi fly forth, powered by their creator's lifeblood into a grotesque mockery of life. All of these constructs, artificial life forms brought into the world by rituals long secreted away in the corners of occult libraries, in the ruins of mighty magical empires and the personal notes of spellcasters with the curiosity to explore this field of arcane lore.
