While hiking in a remote region of Siberia, two young brothers discovered a sanctuary hidden deep in a cave. Contained within the sanctuary was a graven image carved from black granitethat of a great-horned beast. Lying atop an altar at the foot of the beast was an ancient leather-bound testament, which the brothers retrieved and brought back to the monastery, where they lived with their guardian-priest, Father Kirov. He had no idea what dark secrets it would unlock when its writings were translated, describing a covenant made between a young warrior king and the living beast who rose from the depths of hell.
