Burn was once human.

He also had a family and friends, until a metallic angel of death took everything from him. This mechanical monster, Shoftiel, was one of many living machines made to help humanity that revolted and declared war on their creators. It tore through Burn's home and wreaked havoc on his city until the buildings collapsed, crashing down upon them.

Emerging from the rubble, Burn and Shoftiel discover their once separate bodies have become one -- neither human nor machine, but a freak union of both. Internally their minds are caught in a raging battle for control. Just as mankind must struggle against the sentients for survival, Burn must find the strength to overcome Shoftiel's genocidal programming to retain whatever's left of his humanity.
