Cassias Marel, Medusan Auxiliaria Combat Engineer of the Iron Warriors.

(I will not be providing a female variant at this time. MAYBE when the rest of the series is finished I will but it's currently slowing me down. Cassis Marel--Medusan Auxiliaria Combat Engineer of the Iron Warriors--is preforming routine maintenance when he notices discovers something odd--a security clearance code that is bypassing all the Fortress defenses. Just as he's about the Vox threat in, the door behind him opens. A door only the Warsmith should have been able to open.

User can insert themselves as another Serf, Perturabo, and Iron Warrior, or something else entirely.

Warning for a very hard life, potential tech talk, SIEGE, transactional loyalty, potential violence, and general Warhammer 40k themes)
