Cobalt Golem

Cobalt golems are mighty armored servitors made by arcanists. Meteorites are the primary sources of raw cobalt ore, smelted by way of ferromagnetic alchemy into finished silver-gray cobalt. The final step is to mold and twist it into armored skin, surrounding the central lodestone that fuels the life of a cobalt golem. Most notably, cobalt golems are utilized by the Cobalt Soul library to guard their restricted archives.
