Warlock: The Void Patron (5e)
Your patron is the void¸ unimaginable and everlasting. This elder entity has witnessed the original gods and goddesses come to being. Not a soul knows the true form¸ nor the name of The Void. In fact¸ Little knowledge exists of it at all. It is said that it always gazes¸ always grows and consumes. However¸ it is also said that this doubles as a plane of existence. So massive in size that fell beasts are birthed from it's whom¸ and into the other planes.
