Sword of the Gods

2 books
With no memory of his past, a lone hero must fight two battles—one to understand his identity and one to defeat the demon that now plagues Faerûn
 
Demascus wakes up on the cold stone slab of an ancient altar. He doesn’t know who he is. He doesn’t know where he’s from. He doesn’t even know his own name until a stranger tells it to him. But someone—or something—wants to kill him. This he knows with the certainty of the grave.
 
At the same time, a demon from a dead universe—a gift from the Chained God—is freed from its fossilized prison. Its essence takes root in the nightmare reality of the living, sparking a transformation once thought halted by forgotten heroes.

Dodging knives, uncovering clues left by his past life, and dueling demons, Demascus must figure out who he is, who his enemies are, and what battles he is fighting. Along the way, he will discover that he is the last of the forgotten heroes—the only thing that stands between the light of the world and the phantasmagorical torments of the Abyss.
