Imperium

From fattwiki

Imperium, once Empyrean, is one of the first Divines of the Principality. It resembles a huge bird. While in "Armour Astir Pt. 2" there are rumors that it has been leashed by the Principality, it is in fact a willing participant in the imperial project.

It has blessed its Hallowed, such as the squad Imperium's Plume, with extended flight capabilities and, in some cases, a burning aura of authority.
