A rehabilitation session quickly turns into a rescue mission. If you die in the game you die in real life? Please. This is an occupation where a fraction of an inch determines success or failure.

Ambriel was like any other warlock. Brave, powerful, but also curious, hungry for knowledge, perhaps fatally so.
