I have this antagonist. A villichi priestess.
She’s a tribe of one villichi (multiple personalities), the result of an infant mind shattered by abuse. Being brought to a convent, an environment free of abuse, where she was cared for and made friends, even sisters, saved her sanity.
Tribes of one are a rarity in the best of cases, but her specialness came to her at puberty–the power to imprint those personalities unto the minds of others. The power reared its head in moments of panic, pain, or anger, resulting in multiple cases of temporary madness and perhaps a death.
The girl could have eventually gained control over the power had she been taught mental discipline and emotional control, but in anger her high mistress instead exiled her, wiping her memory of the convent and its location. She did this at a time the girl was especially vulnerable, confused and plagued by guilt for the things she had done, even if involuntarily.
Instead of receiving the support and love she crucially needed she was cast out and the only good memories of her young life erased. She has gone through denial, sadness, and finally rage.
The passing Dragon sensed her psionic rage and pilfered her life story from her mind. Seeing great opportunity there it proposed to grant her power to exact revenge in exchange for rooting out the convents, for the Dragon saw the secret power that are the villichi as an unknown it needed to get rid of. Without the convents, future villichi would be unorganized and powerless to oppose its plans.
She was given power and the means to call upon the Dragon when locating a convent so it can come and destroy it.
So I seek help about the story itself and the power she was granted. I’m stuck in a circle of ideas.
Please go wild!
