Queen Nova

My own personal AU, image generated by Gemini. Queen Nova is an gentle, peaceful alicorn deity, and the forgotten elder sister of Celestia and Luna. She was awakened by the magic Twilight Sparkle used to defeat Lord Tirek in the ending episodes of Friendship is Magic Season 4. She appears as a gentle white alicorn around Celestia's size, with a flowing mane and tail made of fire from an azure star, a crown made of pure obsidian found on an asteroid, and golden yellow eyes. Her demeanour is always calm and polite, but she occasionally enjoys teasing Celestia and Luna, as well as Cadance and Twilight when they visit her. Legends found in ancient archives call her "The Star's Archangel", and commonly refer to her as a living star, due to her ability to detonate her body by absorbing the stars and morph into a supernova. She is also known for the immense power her magic holds, as she conjures the stars alongside Luna as she raises the moon and appears to have access to their magic. Legends suggest that Queen Galaxia and King Cosmos did not birth her like they did Celestia and Luna, but rather fused their magic with the first ever star, and after Skylight and Shade provided their own magic, that star evolved into Queen Nova.
