would have liked it better if Candance didn't have a horn. because I heard somewhere that Cadance was a pegasus before she became an alicorn. I don't know if that source was legit but it is my headcanon now
Makes TONS of sense. Also I'm now pumped for the origin story. She probably became a princess when she helped overthrow Sombra, just like Twilight did. Maybe Sombra's artificial. Maybe he's constructed of pure evil by the princesses (who are CLEARLY capable of dark magic) as a "New Princess Test."
