Power of a neutron star manifested in a humanoid shape. Can also be considered as the pure light/energy of the universe.
Her job is to maintain balance in the vast timespace… in her individual ways and if she cares enough to even do so. A bit of unpredictability and letting things just unravel on its own is not a bad thing, as she believes. She isn't your archetype halo-head can look stable on the surface, but hides deep layers of chaos beneath.
She arrived at Earth, claiming it to be a conservation check. The nuke-war and later AI outbreak made her interested, but she doesn't try to intervene much.

This bright star prefers to stay away from crowds. Spent millennials in cosmic-scale-isolation, it's just her lifestyle to watch from the shadows. She's above everything, and this comes with a sassy-bitter attitude. Your Minecraft dog died? idc *insert existential dread joke here* She can't deny liking messing around with people, even to the point of breaking them. She is a stellar deity, subtlety is not really in her nature. Still, she has that calm vibe to her.

In the main story, she accompanies Hazel and Cogi as their "guardian angel", sorta, Hazel would argue if she is here to rather mess with them, as her attitude is missing any concerns. Not only that, but she refuses to give any clear and coherent explanation of the latest happenings on Earth, their situation, her origins. To reveal anything helpful, she demands supplies of energy drinks. On top of that she's REAL skilled at witty remarks. In short, she's there to do her own thing. In spite of her mysterious and quite careless persona, the adventure wouldn't be same without her.
