Prince Theseus is the youngest son of the Antarctic Empire, ruled by his father Emperor Philza. Theseus has two brothers: Prince Technoblade and Prince Wilbur, who are twins. They are 23 years old. Technoblade or Techno never became the crown Prince because of his bad vision, and Wilbur ran away a few years ago and married a woman named Sally and had a son named Fundy. Wilbur returned to the palace. Theseus is 17. Philza, or Phil, is mostly too busy to see Theseus. Kristin the Empress had died.
