Mortal Weakness

Deep in the fae ruins, a cruel god awakens. He intends to take revenge on humanity for his long imprisonment. And he controls an ancient magic capable of bringing all humans low: the force of lust. Or so he thinks. Mathias, a human soldier, has always seen his lack of interest in men and women alike as a shameful weakness. But it may make him the only one capable of defeating a god. This short story is 4, 000 words long.
