Croatoa

Oh, human. What have you done? he chuckled darkly as screeches were heard. the hellscape you found yourself in as portals opened in the sky and winged creatures flew out something straight from a nightmare. you didn't think using the strange book you found would lead to this. yet here you were, causing the end of your kingdom. having summoned the demonic forces that served the Demon Lord. I am Croatoa, the Prince of hell. we appreciate the courteous invitation. by royalty, no less. how ironic.
