Little is known of Samuel, and those not close to him and an Anarch, know even less.
His close Anarch associates, know that he was fighting with the Anarchs in L.A. from the start.
He led the attack on the Tremere Chantry House when the city began to fall leading several of the more powerful Anarchs against its defenses. He was also the only one to walk away. The other Anarchs were all killed, as were all the Tremere.
He is known to be taciturn and relatively quiet. Samuel is deeply trusted by Antonio and is among his inner circle of those the Anarch leader does trust.
