The Healer: Xavier x OC

Synopsis
*This story is set in an AU without MC. There are several changes to the lore, but I've tried to remain faithful to it where I can! If there are any questions, please let me know.*

A mysterious silver-haired stranger saves a lonely immortal woman before disappearing. During their brief meeting, they are drawn to one another in a way neither can explain.

OC:

Sirona is gifted with the ability to siphon lifeforce. This means she can heal others at the cost of her own lifeforce and siphon lifeforce/energy out of others to heal and strengthen herself. When she is injured, she can regenerate, but slowly. Sometimes, it takes hours, but if the injury is life-threatening, she will go into a comatose state and will not wake until her healing is complete. The duration of the coma varies widely based on the severity of the injuries

Sirona's passion is healing and helping others. She has an encyclopedic knowledge of medicinal herbs and uses them to aid her healing process.
