Sarah Willham, a bat who possessed cosmic abilities. She's a very caring, cheery and charming person, but sometimes she does have trust issues at times. Her abilities involves using the sun and the moon. Her powers came from her parents Faye and Vincent that was passed to her at birth. She belongs in a clan known as the Celestials. A faction of regular bats that wields cosmic powers as her all with different types from forming stars to creating a galaxy. The Celestials live in a cave underneath a waterfall at a forest with a nice pond where they could relax and also bathe in the moonlight. Their location is also about 40 minutes away from a residential area full of cities and humans.

At the age of 3, her powers awakened while she was with her parents during a family walk at night during the full moon. Her parents then helped trained her to control her awakened powers. At age 13 at a nice sunny day she was getting some fresh air and she decided to go somewhere private to test her powers. As she was experimenting, her powers had a different effect instead of lunar powers, it changed into solar and it exploded in front of her. The blast was strong that it knocked her down and caused a severe burn scar on her right shoulder. As she got older, her right arm of her fur started to change color from black to blue, but only half way from the evolution of her powers. Since then, she been getting guidance from her parents to help her learn more abilities and helped her control it better.
