 Near the halfway point of the Last War, Merrix d'Cannith, of the Dragonmarked House Cannith, was commissioned to build a great army of golems, to serve as untiring warriors.Not satisfied with the lifeless, unintelligent hulks his forges produced, nor with the prohibitively expensive process of creating golems one-by-one, Merrix began experimenting with magic to instill some spark of life in them that would enable them, like living things, to direct their own actions and to be grown by a self-sustaining process.After many unsuccessful attempts, Merrix's son, Aarren d'Cannith, finally invented the process used in the creation forges.
