Pasanius Lysane
From Lexicanum
Pasanius Lysane was a Veteran Sergeant in the 4th Company of the Ultramarines Space Marine Chapter.
The best friend of Uriel Ventris from childhood, the pair remained together throughout their training and subsequent service in the Ultramarines. He was the largest out of all in training and the company, so he had to wear salvaged Tactical Dreadnought Armour to fit his frame. His primary weapon was a Flamer.1
Pasanius went with Ventris into exile from the Ultramarines Chapter after the Tarsis Ultra incident, where he was complicit in helping Ventris break the strictures of the Codex Astartes.2 Surrendering rank and all Ultramarines insignia, they pair were sworn to a Death Oath. They were eventually successful in completing the Oath's vows3, and recently returned to the domains of Ultramar.
Pasanius's Lost Right Arm
When 4th Company ventured to the planet Pavonis in order to quell the civil uprisings there, they found more than expected. Dark Eldar raiders were working in league with a cartel member, Kasamir de Valtos, to summon a C'Tan, the Nightbringer, and it's ship. When the company was fighting the C'Tan, Pasanius lost his right arm to the C'Tan's blade. He received a bionic arm replacement, but it felt unusually cold to the touch, and gleamed a bright silver.1 It eventually transpires that the metal his bionic arm was made from was actually the living metal of the necrontyr, which meant it had the ability to heal itself, given time. Pasanius kept this regenerative ability a secret, fearing the consequences should it be discovered he had such an unnatural power. Disgusted with himself and interpreting the bionic arm as a sign of moral corruption, Pasanius regularly scourged himself in an attempt to do penance.
He was eventually divested of the arm upon the world of Medrengard, during his exile from the Ultramarines.3
