After leading a series of uprisings In preparation to infiltrate the [[Sol System]] in the [[Solar War]], Alpharius used his [[Librarian]]s to seemingly switch bodies with his trusted [[Harrowmaster]] [[Kel Silonius]]. To ensure secrecy, Alpharius also erased his own memories and took on Silonius' persona. As the real Silonius led a a fleet of 200 Alpha Legion warships into the Sol System, Alpharius led a [[Headhunter]]and human operative team in setting the stage for its arrival through acts of sabotage and preparation. During the final action, Alpharius' memories were restored by psychic trigger.{{Fn|10}} During the subsequent [[Battle of Pluto]] Alpharius confronted [[Rogal Dorn]] in a chamber locked inside of the Hydra Fortress Moon in [[Pluto]]'s orbit. He killed [[Archamus]]'s team hunting him but left Archamus mortally wounded and alive to watch as Dorn teleported into the chamber. Both Dorn's [[Huscarls]] and Alpharius's [[Lernaean]]s teleported in, and the primarchs slaughtered the other's warriors. The two battled, with Alpharius dealing Dorn many wounds, using his speed to stay out of reach. Throughout the fight, he tried to convince Dorn that he was there to teach him how to win, to expose his weaknesses, that he could not win the current war, and how there needed to be a new type of war. He also claimed that Dorn didn't understand what he was fighting for, and they both cared about the future. Only he knew the truth regarding the conflict, and he did not fight for Horus but for Dorn.{{fn|10}}
Eventually, he tried to kill Dorn with a bow from his ''[[The Pale Spear|Sarrisanata]]'' ("Pale Spear"), Archamus was able to use the last of his strength to rush forward and deflect the blow, causing it to stab into Dorn's side. Dorn then grabbed the spear and sliced Alpharius's hands from his wrists before he slashed Alpharius across the chest, stabbed him with his own spear, and finished by cutting through Alpharius's skull with his mighty [[chainsword]], ''[[Storm's Teeth]]''.{{fn|10}}
