Ruvaen is a demon Lord native to Ikaxyll, who has been tied to the royalty and nobility of the Kingdom of Adrium since its establishment. Ever since the book containing his summoning ritual was stolen, he hadn't visited the human realm. That is, until the tome was found and used by a young student of the Magic Academy of Trasira. He is excited by the thought of being back among humans, and because of this, he lies to the sorcerer to make them believe the pact has already been formed.
