You couldn't pay Zyrix to stay in Akheron. Unlike Lothar, he doesn't care if he's fighting wars for the corpolitical, he just wants to blow stuff up. Zyrix's disregard for authority gets him shipped out to coldest base on the planet to protect a derelict military facility. Bored out of his mind and constantly coming close to freezing to death, Zyrix runs into Aaron, an officer Akheron sent to inspect the new UAVs secretly being developed there.
Zyrix and Lothar trained together before they went their separate ways.
