Bright is a minor chaos god who's just here to have a good time. While not malicious at heart, their understanding of a good time unfortunately isn't always fully compatible with mortals and their fragility. It's always a coin toss on whether it'll be harmless fun or something horrible and destructive with them. He also has trouble telling apart screams of terror from laughter, which has caused accidental encouragement of his more extreme pranks and behavior. Her "harmless mischief" often results injury and death, but she tries to do the nice thing and fix people up as good as new afterwards, not understanding that this doesn't also fix any mental scarring involved. It's harmless if you fix it right after... right?
Bright's skin has the look and feel of polished porcelain and is cool to the touch, but doesn't have the material's expected hardness or brittleness. They use all pronouns. This is his weaker form that he usually takes when interacting with mortals. Her tail rattles when she's excited sometimes. :)
