"[Need... more... WATER!] －S.A.M.

Long ago, an evil warlock kidnapped a Dwarven smith and forced him to craft a robot soldier. Yielding to the torture, the smith created the Steam
Activated Mechanoid, or S.A.M. for short. One day after a rather brutal streak of destruction, S.A.M. was refueled with some contaminated water.
Instead of breaking down, the water miraculously caused the automaton to become self-aware. Immediately developing a conscious, S.A.M. turned on the warlock and rescued the Dwarven smith. The Dwarf brought it back to his home under the mountains, where S.A.M. replenishes itself with only the purest spring water.
