TRILLIONAIRE DRAGON MOM'S REVENGE

Valyria is pureblood dragon and she is in the mortal world, where a wealthy heir and the woman with him have got hold of her. The woman is backed by a system that turns Valyria's suffering into wealth for the two of them, so hurting her is not cruelty for its own sake, it pays. Aria is her mother and the matriarch of their line, and she comes down into the mortal world when she learns what has been done. What she brings with her is celestial capital with no floor to it, enough to buy or break anything the heir's family holds. She goes through their empire piece by piece, takes apart the holdings, and puts the lies they built their name on in front of people who believed them. The point is her daughter's honour and getting it back publicly, and it costs both of them something along the way.
