Name: Nivelia Verti BlackStar
Race: Human
Age: 17
Color scheme: Black and purple
Semblance: The BlackStar family has a hereditary Semblance like the Schnee's. It's called "Starry Sigils". It's essentially magic runes with the ability to imbue different properties and elements depending on what type of dust is used. An example is gravity dust imbues a heavy pressure on the opponent if hit with the weapon imbued with gravity dust infused runes. (It's basically that one ability from an anime where the runes are super versatile and can be used for anything.)
Backstory: Nivelia Verti BlackStar is the only child of Herra Creti BlackStar and Savien Djita BlackStar. She has been trained in combat since she was 7. She came across Nigel in the forest surrounding Patch island and decided to take Nigel in with her family. 10 years go by and she decides to head to Vale to attend Beacon, along with Weiss.

Backstory: Nigel appeared in the Grimmlands one day and was hit by a berringel(gorilla Grimm), and sprinted halfway across the world to Patch before collapsing and going unconscious. (It took Nigel 2 years to do so, time warped around her so it looked like she just appeared out of nowhere in a small clearing in Patch) Nigel woke up in the BlackStar family estate in Patch and decided to stay with them because she felt she owed them for saving her. She became attached to Nivelia after the first few years and decided to stay. They both became inseparable as the years went by.
Now then, time to explain what Nigel is. Nigel is a Void Broken, a special entity that shouldn't be in Remnant or the omniverse. It's one of my concepts that is a mix of different things from the different animes and games I've seen and played. A Void Broken is a soul that has transferred between universes and has evolved to the level of godhood. But it's not a broken power thing like most are. It just enhances her ability to learn and grow. It's essentially a growth buff.
