Queen Celestia
Once, long, long ago, there lived a unicorn whose beauty was such that suitors came from all corners of the land to ask for her hoof in marriage. So beautiful was this mare that she even captured the attention of the gods, who would gaze upon her from their home on Mount Olympus. Only one would dare descend to see her, however; Helios, the God of the Sun, broke the celestial rule against liaising with mortals to behold her beauty in person.
