House Hermetika is a loyalist Knight House from Kaldeia, allied to the forge of Mezoa. Over the centuries the Knights of Hermetika and the tech-priests of Mezoa grew close — the house’s ascetic practices penetrated the rites of Mezoa’s Machine Cult. When Horus advanced through the Cyclops Cluster, more than a hundred Hierarchs (Knights) joined the forge’s Taghmata, repelling the invasion by the Dark Mechanicum and the traitor Legions (the defence of Mezoa, ~008.M31).
