Burning of Boletaria

The Burning of Boletaria was one of the darkest days in the history of the Seraphim of the Abyss Chapter, when their Chapter homeworld of Boletaria was destroyed by an invasion by a large force comprised of Fallen Angels.

History
A battle that has been shrouded in secrecy and suspicion brought by the Inquisition, the Seraphim of the Abyss were borne of this terrible and harrowing incident. But what is known is that the Feudal World of Boletaria was destroyed during a bloody void war engaged above the planet, and that the Seraphim of the Abyss were locked in combat with an unknown and ferocious enemy. Even though they were clearly outnumbered by the foe, they denied any requests for aid as they defended their home.

The Fallen Angels had assembled in great strength and sought their own vengeance on the isolated Chapter, until the Materium was torn open and Warp Rifts appeared across the galaxy, and Boletaria was torn apart by a newborn Immaterial Rift close by. In agonizing grief, the Seraphim of the Gryphon fled the system as the Warp-tides inadvertently destroyed much of the Fallen fleet. Their world demolished and their oaths failed, the Chapter became the Seraphim of the Abyss and their burning hatred for the heretical traitors multiplied by hundreds of times as they quickly rebuilt their ranks and immediately set out to hunt down their aggressors.
