Description
A unique form of a classic arcane construct, cobalt golems are mighty armored. servitors made by arcanists who find iron too mundane a metal. The first seeds of these automata fall from the sky, with raw cobalt carefully extracted from meteorites and smelted by way of ferromagnetic alchemy into a hard, lustrous, silver-gray metal. This finished cobalt is then molded and twisted into armored skin shielding clockwork designs that animate rune-encrusted muscle-like chains. A central lodestone powers a cobalt golem, fueled by magic rituals that spark ionized life within its inorganic shell.
Archivists’ Automata. The Library of the Cobalt Soul has commissioned a large number of cobalt golems to guard their most restricted archives, taking pleasure in the serendipitous nature of the construct’s name and trusting the threat of these powerful warriors to deter anyone thinking of fleeing with sacred knowledge.
