No more like the goddess is a real divine being and the goddess in the palace is just a puppet... But realistically if a sorcerer was that strong to be able to summon other world beings she wouldnt really need them since she could probably kill the demon king by herself. (๑•ㅂ•)و✧
She’s probably not a goddess if she’s sitting in a palace where people can go an personally see her. She’s probably just a powerful sorceress.
