Continuing my concepts from “Dream War”.
The Demon is an old Native American deity, which wants to take revenge on people who abandoned their beliefs and condemned it to oblivion. Now after years it awakens and is still too weak to attack frontally, thus assaults residents at night during their dream, driving them mad. People go into a coma and through demonic corruption change into monsters serving a new lord.
With every corrupted human the Demon grows stronger. It’s ultimate goal is to break the barrier between the dream and the real world.
