Born Foma of the Taiga to human peasants in a forgotten village in the middle of the Siberian Forrest. Whilst hunting in the forests in his late teens, a crazed unknown rogue vampire attacks him. Due to his size and the rogue's weakened state, Tommas injures them enough there is an exchange of blood. The reaction of the vampire enzyme with his diabetic blood sent him into Blood Madness. Having recently gorged on bear meat, he changed into a bear-man and, lost in the throes of blood madness, became a beast of the forest for nearly a century.

In the early 1800s, GEMMA GOSCOTE comes across him, recognises what he is, and saves him. He fell in love with her and the pair have been together ever since.
