Shortly after commencing the action that purged the Tyranid infestation on Algol, Severus led a small squad of newly initiated Space Marines from the 2nd Company to Mithron to answer an Imperial Fists’ distress call from the 5th Company garrisoned there.
Not long after Ultima Squad had made planetfall and skirmished with a contingent of Black Legion Chaos Space Marines, the Ultramarines were attacked by a Chaos Daemon Prince who was leading the attack. Severus was presumably killed when he and the Daemon Prince toppled out of a high window, and fell down a deep chasm below.
The Prince then tore away Severus's flesh and "wore" it as a disguise, to reunite with the Ultima Squad and infiltrate the Strike Cruiser that had delivered them to Mithron. It revealed its true nature, and was killed by Proteus before it could fulfill its plan to return with the rest of the survivors to Macragge.
