Nicolae Danrigakopf, more commonly known as Sky King Vol'star XII by the Avens of Arade, is a 24 year-old summoner of flying creatures out of Bucharest, Romania. He was originally a human at birth, but it was later revealed he was maturing into an Aven. This first recorded incident appeared when after his first victory at the Academy of Magic's dueling arena, against his later long-time ally Cassy Tomb, when dark blue feathers appeared on his hand. He is a tall youth, nearly 6'1", covered in dark blue feathers with same colored wings, except the insides are a heavenly white, showing that he is of Aradian origin. How he learned how to summon is unknown at this time.
