Are minis from 2004 Oldhammer?
A cogitator, a gift from the Machine God, is a marvel of ancient technology. From the humble hand-held device, humming with a spark of divine consciousness, to the colossal cathedral-sized mainframes, dreaming of the fate of worlds, cogitators are the lifeblood of the Imperium. They store the secrets of the ages, calculate the trajectories of starships, and guide the righteous hand of the Tech-Priest.
