Pasanius Lysane

Pasanius Lysane was a Veteran Sergeant in the 4th Company of the Ultramarines Chapter.&nbsp

He was the best friend of Uriel Ventris and the pair remained together through their training and subsequent service in the Ultramarines.He was the largest out of all the others in the training and the company, so he had to wear salvaged Tactical Dreadnought Armour to accomodate his size. His primary weapon was a heavy Flamer.

Pasanius went into exile with Ventris following the invasion of Tarsis Ultra by a Tyranid hive fleet. He willingly broke the strictures of the Codex Astartes to join an Ordos Xenos Deathwatch squad, kill the Tyranid Norn-queen and stop the invasion. Surrendering both rank and the Ultramarine insignia, both Pasanius and Ventris were made to swear a Death Oath by Marneus Calgar.

This Death Oath was to seek out and destroy the daemonculaba. They fulfilled this Death Oath when the travelled on the Omphalos Daemonium, an ancient daemon engine, to the world of Medrengard. This world was engulfed in civil war as the palace of Warsmith Honsou was laid under seige by Warsmith Toramino and the Chaos Dreadnought Berossus. They enlisted the help of former Raven Guard Ardaric Vaanes and his group of renegades and infiltrated the fortress at the height of the seige. However, they were captured by the daemon-possesed Iron Warrior Onyx and taken to the halls of the Savage Morticians. Once there, Uriel was entombed inside the womb of one of the daemonculaba and Pasanius had his bionic right arm removed. Uriel miraculously fought free of the womb and he and Pasanius escaped down a sewage chute. They were finally able to return to the fortress, fufill their Death Oath and return to their Chapter.

 Pasanius' Right Arm 

When the Ultramarines' 4th Company ventured to the world of Pavonis to quell an uprising, they found more than they had expected. Dark Eldar raiders were working with the cartel member Kasimir de Valtos to free a Necron C'Tan, the Nightbringer, and its ship. Pasanius lost his right arm to the Nightbringer's blade, fighting it deep below the surface of Pavonis and had a bionic arm attached afterwards. He eventually discovered that his arm was made from necrodermis, the living metal of the Necrons. This metal would slowly heal itself over time and, once he found out, Pasanius kept it hidden from the rest of the Chapter for fear of what they might do. Pasanius had this arm removed by the Savage Morticians on the world on Medrengard, during his exile from the Ultramarines. Once they retuned Pasanius was forced to leave his Company for 100 days for not revealing what his arm could do.
