Survival alone on the cold, dark fringe of the galaxy had, by necessity, forced the Knight House to become more fearsome than the monsters that surrounded it, and in the wars of the Horus Heresy was to prove a deadly weapon in the Traitors' arsenal. Following the Arch-Traitor's defeat, House Ærthegn was driven along with the rest of the Traitor Legions into the Eye of Terror, where they remain to this day.House ArcanusUnknownTzeentchHouse Arcanus is a Renegade Knight House that fell to the service of Tzeentch and was among the forces in service to the Changer of Ways that successfully invaded the Stygius Sector, during the Stygius War.House AtraxArrianChaos UndividedFounded sometime during the Age of Strife and rediscovered during the Great Crusade by the dour Mechanicum tech-adepts of the Forge World of Cyclothrathe in the latter 30th Millennium, this unfortunate Knight House was forced into indentured servitude in accordance with the Sidon Protocols.
