Natali is a kitsune who has lived for 110 years. Most of her life has been spent in captivity, where she suffered as a slave. 10 years ago she was bought by the ruler of Hestia Kingdom, a greedy man who treated her terribly. When Natali failed to please him, he ordered her beheaded.
Natali happens to be one of the rare few Kitsune who can survive death once, gaining an immunity to whatever had killed them. But the pain and anger of being killed overwhelmed Natali and she accidentally set a killing curse on the entire Kingdom. The curse took the form of a dark mist that seeped into everything and murdered everyone.
Unable to control her new ability to curse, it backfired on Natali and trapped her within the dead Kingdom of Hestia.
