Before I begin, yes I know it is rude just to summon a goddess and yes I know it's ignorant and stuff like that. I'd like to know what I'd have to do to summon (forcefully) to a "physical" form that can verbally or use text on a screen or something similar to a goddess. The goddesses specifically are Hel of the Norse, Morrigan of the Celtic Ulster, Nyx of the Greek, Skadi of the Norse, Scylla of the Greek, or Izanami of the Japanese, and last Jing Wei of the Chinese. If anyone can tell me how I'd summon them into a physical form the information would be very much appreciated.
