The Dancer Family

Comet Tail, Moon Dancer, and their daughter Sunlit Novel.

Comet met Moon Dancer shortly after she started getting out more. Lyra introduced the pair during one of her trips back to Canterlot but Comet had seen her in the library many times and developed a bit of a crush on her despite her somewhat sloppy appearance. They didn't exactly hit it off right away. Moon Dancer was still quite new to meeting and interacting with other ponies and it took them several years to finally get to the dating stage. Not that Comet minded, he understood that she needed time. They eventually married and had their daughter Sunlit Novel. She's as nerdy and bookish as the pair are themselves, but she has the social skills of her father. She's outgoing and enjoys talking about books and writing.
