The Lost Sons

Founding
The Lost Sons were amalgamated from Renegade Astartes bands who joined St. Athaliah the Flame's mini-crusade to escape the Eye of Terror defending the Saint and her motley assemblage of followers. The Sons come from a wide selection of Chapters, many now non-existent or perditus, and some had been trapped in the Eye for a millenia or more. Many refuse to discuss their origins and some may genuinely not remember them.

Favored Weapons/Tactics
The Sons prefer melee weapons to ranged ones and their bolters have weighted butts so they can be used as clubs. Many brethren are armed with relic blades liberated from the collection of Trazyn the Infinite (long story) along with several captive Astartes who joined the Sons. Artificers serving the Chapter forge slightly curved, single edged power sabres.

Chapter Culture
Because of their disparate origins the Sons strongly emphasize Brotherhood among Astartes, and between Astartes and normal Humanity as well.
