Brightlight Sparkle Sentry I (also know as Brightly, Bri, daddy’s girl), she’s the pride of her parents, she has the intelligence of her mother, the courage of her father and the adventured-side of her grandmother. It was a surprise (again) when they notice that the newborn filly was actually an alicorn, specially for mommy Twilight who who spent many weeks in the library looking for answers to the unusual phenomenon, and Flurry was definitely not very happy to know that her cousin was also like her and she could teach her how to take care of her feathers and brush her mane so that she didn’t get entangled in the wings, and to not exploit magical artifacts by accident.
-Little Brightly LOVES her daddy, especially when she tells stories of brave soldiers and furious dragons, or when he prepares her favorite waffles (especially if it has strawberries on top!). When she grows up, she wants to be like him, which her mother doesn’t support much but she thinks is very adorable to catch her daughter using her father’s helmet and pretend to take care of the entrance to her room.
-Brightlight visits her grandparents very often in Canterlot, and many times she has to spent the night with them because her parents have had important royalty issues to attend to. Not that it bothers her, on the contrary, she loves to hang out with Grandma Velvet and Grandpa Nighty! sometimes they even take her to the movies when she is supposed to be sleeping, or eat ice cream while playing in the gardens of Canterlot.
-Brightlight was born with a defect with her magic; Like Flurry Heart before the Cristalling, she has huge waves of accumulated magic without control; and although a Cristalling-like ceremony was performed in an attempt to control it, her magic is simply unstable, to the point where performing the minimum spell there is a risk that something will explode. Brightlight doesn’t seem to bother much about the fact that she can’t use her horn, she feels comfortable with just the wings.
