A reference for my sona Astra.
Lore: Astra used to be a star spirit without a physical body. She was a bit of trickster, but had a heart of gold. She spent thousands of years in this state until she ended up sealed in a flash drive somehow. A person ended up buying it, intending to use it for work stuff, but he accidentally bumped it and it fell into his cat Daisy's food bowl. One thing led to another, and Daisy ended up eating the flash drive and giving Astra a physical body. The person was surprised to see that his cat had become something completely different than what she used to look like, walking on 2 legs and talking, but Astra decided to set off on her own to experience what human life was like. (And yes, Daisy is completely fine with Astra taking over her body.)
