Conflagrant Host
From Halo: Daybreak
The Conflagrant Host is a micro-faction of pirates that operate in a 100-lightyear bubble on the fringes of the Refuge of the Forsaken in the Siakar Expanse. Little is known about them, though they are believed hostile to the UEG, and concern themselves with raiding fringe worlds. As of 2558, they have been unable to establish themselves as a proper polity, making it likely that they will be eradicated or splintered like many other similar groups.
