Legio Inferna Viridi

The Firewyrms Legion is a titan legion based on a forge world Magna Cupal in Vigilius sector, Ultima Segmentum. It was found after the reintegration of the forge world into the existing Adeptus Mechanicus during the Great Scouring and has since fought on innumerable worlds across the segmentae. The Firewyrms Legion holds rivalry with the Legio Ardens Aestus titan legion which headquarters also lie within the Vigilius sector.

Most of the legion is made up of the warlord battle titans which are coupled with a dozen reaver battle titans and warhound scout titans. The Firewyrms have access to two imperator titans; Excelsior and Drake Invicta.
