Peter Steiner-Davion

Peter Steiner-Davion was the third of Hanse Davion and Melissa Steiner's five children. He was born on February 2, 3035. As such, he was to be the regent on Tharkad and of the Lyran half of the Federated Commonwealth while Victor was holding court on New Avalon. Due to his sister Katherine's manipulations, however, this did not work out.

Peter, following in his older brother's footsteps, attended the Nagelring, the premier Lyran military academy. He was, however, manipulated by his older sister and sent away by his brother, so he went into and exile of sorts. Unbeknown to Katherine, he retired to a monastery for ex-MechWarriors on Zaniah III that had been the home of Morgan Kell.

Peter was pulled from his exile by Morgan in 3067 when it became clear that the Lyran Alliance would need a new Archon to bring an end to the FedCom Civil War. Peter led a pan-Lyran coalition to Tharkad, though he attempted to convince his great-aunt Nondi to retire peacefully before landing his troops. Peter's forces gradually pushed Nondi's Loyalists back to the capital, where he killed her in single combat amid bitter street-to-street fighting in his new Fafnir.

Victor abdicated as Archon-Prince and decreed that Peter be his successor in the Lyran Alliance, though that precluded him from ever claiming the Federated Suns throne on New Avalon. Peter set about rebuilding the Lyran military and much of its ruined infrastructure.

An opportunity arose to gain help when the Star League Council convened in late 3067 on Tharkad. On a personal level, Peter sought to patch up his damaged relationship with Victor before the Council convened. Rather than ask the League for help, however, Peter decided that he would pull the Alliance out of the League. This decision would have dire consequences when the Word of Blake, incensed that their interpretation of a cenuries-old prophecy was seemingly foiled, attempted to cow the Lyrans back into the League by threatening them with bombardment from the Star League-era LCS Invincible. When the Lyrans refused to bow to the pressure, the WarShip launched a devastating assault that ruptured an underground nuclear power plant.

Peter tried to lead his people from the besieged capital, but only a daring assault meant to rescue him managed to get a message of hope out to his subjects. In time, the Brotherhood of Cincinnatus ousted Peter and replaced him with a "purebred" Steiner Archon.
