Moff Pyron rose to prominence in an Empire that was in flux. One of the youngest officers to achieve the title of Moff, Pyron felt it was his duty to fulfill his commitment as a soldier and not get involved in Sith affairs. He held fast to this policy, until Darth Thanaton canceled his pet superweapon project‒the Silencer.
Believing that Darth Thanaton's motivations for canceling the Silencer project‒an insistent reliance on Sith tradition and the use of the Force over new technology‒were ultimately self-defeating, Moff Pyron decided it was time to seek alliances elsewhere among the Sith. He had come to realize that both his own advancement and that of the Empire depended on realigning one's most deeply held principles.
