Periastron is a part of the PHIGHTING universe, they act as a false deity. Many of the other demons worship them despite them explicitly saying that they, in fact, are not a god. Periastron has sharp, short ivory horns and illusionary wings adorning their head. They usually wear white robes and armor, with black accenting accessories. Periastron acts detached and emotionless when in reality they are simply quite shy.
