After enduring years in a world of monsters, betrayal, and endless struggle, he returns to the past with ten years left before disaster strikes again.

As a ruthless instructor with memories of hell itself, his methods are harsh, strange, and often terrifying, but every lesson carries the weight of a war only he remembers.
