Bao

Note- the form you see here is Bao's 'true' form and is comparable in size to a bobcat (but a lot longer and snakier, of course). If trying to be sneaky, Bao can take a purely domestic feline form that's dark brown with white points (kinda like her tail in true form) although her 'antenna' are there regardless.

Bao's magic allows her to offer a unique gift to anyone who can pay the price; she will offer an additional, illness-free year of life to anybody who can provide her with their (literal) weight in gold. The price is repeatable and she doesn't give a hoot about how the gold is actually acquired; it can be a gift from another, stolen, or just from a really rich person. She absolutely loves the stuff and hoards her gold in various strange pockets around the world.
