Serivahn
Serivahn is the Emperor's Spears Primaris[1a] Shipmaster, of the 3rd Warhost's Strike Cruiser, Hex.[1b]
However, his Primaris Gene-seed implantation failed in the Alpha and Beta phases, which caused Serivahn's body to become heavily disfigured, with misshaped limbs and left him in constant pain.[1a] This was largely due to the Great Rift, whose creation left the Spear's Homeworld, Nemeton, and the other worlds of Elara's Veil, cut off and isolated from the wider Imperium. It was only due to the arrival of a small Imperial strike force that the Spears were able to gain access to the information needed to create Primaris, but unfortunately not the technology to safely do so.[1c] This led the Spears to a tragic journey of trial and error that caused the deaths of numerous Aspirants[1a] before Serivahn miraculously survived. Using what they learned from his procedure, the Spears were able to perfect their Primaris creation and Serivahn would became known as the First Primaris Spear, though he thinks of himself as only the first to survive. However, because of his disfigurements, Serivahn was not capable of physically joining his Chapter in battle and instead became the Shipmaster of the Strike Cruiser Hex.[1c] The Tech-Priests of Bellona proposed to replace all of Serivahn's crippled parts with bionics, but he refused.[2] Despite his appearance though, Serivahn is treated as a true Space Marine by both the Battle Brothers of his Chapter[1c] and their Celestial Lions allies, who all have great respect for the Shipmaster.[1d]
