Asmodis

One of the Trinity of Shadows, eternal enemies of the Ashtari pantheon.
He's known as the Enslaving God. He rules over blood betrayal, slavery, mindlessness, madness and undeath. He is lord of chains, that which thrives in the darkness and on the sentient species. He is said to be chained beneath the sands in the fabled proto-elven capital, surrounded by his countless undead slaves. Anyone who unearths one of the ruined complexes from the sand will face horrors from the worst of nightmares, hungry for the flesh and fluids of the living.
