Ygraine Blackthorne

Lady Ygraine Blackthorne (later known simply as Sister Ygraine) was the youngest child of Lord Lamorak Blackthorne by his wife Morgwyna Monmoth. Alongside her elder sisters, Evaine and Isolde, they formed the She-Griffins Three, a group that helped oversee the running of House Blackthorne during their wars with Brecilidia in the early 500s. Ygraine was her parents' favorite and beloved too of her sisters, known for her boundlessly sweet nature and optimism. Her sisters' differing outlooks often made them fight, and it was on Ygraine to be the level head between them, acting as go-between and having final arbitration as to their best course of action. She was considerably more credulous and pious than many of her kin, or many westerners in general.
Ygraine left with her sisters when they were passed over for succession in favor of her cousin Allister. Their mother was sick and ailing following the death of her father, and as her sisters fought each other on what to do next, Ygraine busied herself with looking after Morgwyna. When the three eventually split and Morgwyna died, Ygraine joined the priesthood, becoming a volunteer and missionary in helping the homeless and needy--far way from her noble roots. She was well-respected in the church and on one occasion turned down the office of Archprimate, believing the duties would distract from her good work too much. She lived to great old age and was still considered bright-eyed and energetic into her nineties; unfortunately, her readiness in helping the sick proved to be her downfall. She passed from a disease she caught from a homeless woman in her care in 590AE, leaving behind no issue following her vows of chastity.
