Just discovered this, if you still have room. Have a character I created in a medieval (non-D&D) setting that might work.
My pitch: The Magdalena
As magic started to return to the world, the Church grew concerned. After all, it was magic that had burned the world to ash. What little magical divine power remained to the church was carefully gathered together in a secret, ancient ritual. It was then poured into a carefully chosen vessel. For some reason, this needed to be a girl of around ten years of age. Taken from her family -- or, ideally, a child of no family -- she was carefully raised and trained in a cloister by the church, not only in the use of her divine powers but also in combat, for she would be the church's weapon against magic resurgent and other evils of the world, such as vampires, werecreatures, demons and devils, undead, and other unnatural entities resulting from the magical destruction of the world. Thus was the line of the Magdalena born. Given their line of work, they tend to be short-lived, rarely reaching 30 years of age.
Magdalena is currently the seventh of her line. Her parents were poor peasants, her father a carpenter. In exchange for their daughter, her father was given work and a generous wage, a guaranteed family home paid for by the church, and a blessing of fertility to replace their daughter. But they were never to see their daughter again.
Magdalena did exceedingly well in her training. But she was restless and longed to see the world outside the cloister. One night when she was sixteen she escaped out into the city. It was an entirely new world for her. She used her training to keep ahead of the church agents searching for her, with the aid of a helpful (and handsome!) young thief from the streets. She spent a glorious week of freedom and young love.
But her happiness was not to last. She had a calling. She belonged to the Maker. After a cat and mouse chase with church agents, she and her beau ducked into an old building. Unfortunately this building had recently been claimed by a group of were rats. Magdalena felt the surge of the Maker's power inside of her, and she fought magnificently alongside her beau, but there were many, and her beau took a rapier through the chest before she finished the final foe.
Desperately Magdalena tried to heal her beau, as she had been taught, but she found the power of the Maker unresponsive. With tears smearing the blood on her face, she realized the choice that needed to be made. Once she resolved to return to the cloister, the power flowed again, and her beau breathed once more, his fatal wounds healing fully. The agents of the church found her there, holding him in her arms. She went willingly with them, never to see her young love again.
In the two years since, Magdalena completed her training and has now been sent out into the world to serve as the Maker's avenging arm against magic and evil.

Basically it's a Vengeance Paladin, and since we don't have a healer in the party, she might be helpful
Could also conflict with our sorcerer a bit.
