Pyre

The Pyre is a warband of Chaos Space Marines of unknown origin, most active currently in the Jericho Reach. The Pyre warband were first observed by Imperial forces near the Eye of Terror in 131.M41. There are no confirmed records of encounters with the warband prior to this time. Departmento Munitorum analysts have not been able to determine if The Pyre splintered from another known Chaos warband, or if they were assembled from fragments of several different groups. There are also no indications that The Pyre holds fealty to any Chaos God; instead they seek to coordinate their battles with servants of all the Dark Gods. The Pyre are known to have operated at some point from the space hulk known as the Unholy Harbinger.
