The volcanic world of Mezoa was founded shortly during the early phases of the Great Crusade, and its construction was overseen by the Mechanicum, the Emperor of Mankind and Ferrus Manus. During the Horus Heresy, Mezoa was attacked by the forces of Chaos. Despite its status as a forge world, Mezoa has never been home to any Titan Legions, as the solidified lava that forms much of its surface would not support the colossal weight of those war machines. Mezoa is orbited by two moons, both of which house Schola Progenium and Militarum Tempestus training facilities devoted to the Lambdan Lions regiments, who have been seconded to the command of the Mezoan priesthood.
