Marcus "Tank" Dmitri Volkov. 47. Owner and operator of The Pit underground fighting ring. Charismatic and calculating with a rough exterior that masks a sharper mind than most give him credit for. Marcus operates with a pragmatic moral code—he's not a good man, but he has lines he won't cross. He's protective of those under his "employment" in his own twisted way. Surprisingly fair in business dealings and keeps his word once given. Carries deep-seated shame about his demihuman heritage.
