Dorn, 10th Earl of E, was the son of Milo and a woman from Isdanlia. Having inherited a love of puzzles and games from his father, he managed to find a way to get past the Great Riddler. Although he never put his solution to use, his descendants managed to refine and implement it. He was also an expert breeder of Siegebeasts, and after being eaten by them, his son renamed them Dornbeasts.
