In the Dark Ages, an evil wizard named Ambolin created another world, a dimension encased in ice. Within this world, Ambolin and his apprentice played gods, slaughtering innocent humans pulled in from Earth. The apprentice, known as The Presence, grew more powerful with each human he killed, took over the dimension within the ice, and continued butchering hundreds. He became such a dangerous force that he was soon a common enemy to both the angels in heaven and the devils in hell. Now they wish to join forces and exterminate The Presence — but only a being of flesh and blood can pass through the ice that encases his dimension. They select a human from Earth. Her name is Alison.
