First time attempting DW and posting on CGsociety, not much time left but let's try!
God of dreams
The basic concept is a God that can travel across the dreams and from time to time he picks one of his followers to make his dream come true, but only if they accomplish certain missions.
In the good dreams, the God's appearence is soft, gentle and inocent like a child.
In the bad dreams/ nightmares, the God's appearence is sinister, he looks like an evil beast.
They're the same entity, but splitted into two bodies.
The missions vary from follower to follower, but the ones in bad dreams usually brings greater rewards, they're the hardest ones and you have to confront your worst fears. The ones in good dreams sometimes only benefits the God himself, he can be a bit selfish, you know.
Those are the first sketches of the God that appears in the "good" dreams.
