gist of it, she's cursed from birth thanks to being the child of a sole survivor of the crimson moon dynasty of khaenri'ah. she's pretty much herself now the only living member of it.

it iirc not only changed her arms into those claws and marked them up, but also plagued hers with nightmares, hallucinations, and causes her to having an unnerving presence. though that's also from her strength too, she also thanks to it has her body lit up hotter then a volcano and doesn't need her pyro vision or delusion to use the fire from it.
