we know not of where they came from or who he is but he is one of the stars (aka gods) of the Multiverse. He rules the Door Dimension with Slenderman (YASSSSS SLENDERMAN REFERENCE BOIIII) as his personal assistant.
Personality: mysterious, eerie, mysterious.
He used to be normal until he got chosen to be a Star. He did not want that life, but he could handle it if it meant having Ozzy, his husband, with him
