Sir Billiam III owned the mansion where the Masquerade took place. He may be the ancestor of Technoblade due to their similar anthropomorphic appearances and the Egg finding Technoblade "familiar." Other similarities include both being wanted criminals (and sharing similar wanted posters), both loving money, and both admiring withers. At the end of the event, Sir Billiam III revealed that the Egg, which he nourished in his basement, had indoctrinated him.
