Celeste of Merinita, fillia of Lambert of Merinita
Celeste was born at the covenant of Irencillia, the daughter of the local woodworker, and a local witch. When she was 7, her mother died, but the circumstances of her death were kept vague. Shortly after, she began to see her mother's ghost, who sought to draw her into finding out how and why she died.
When Lambert came to visit, he noticed something that no one else paid any attention to. While she didn't cause any averse reaction from the covenfolk, his animals had the same reaction to her as they did to most magi. And when he discovered that her mother's ghost haunted her, he was convinced that she was Gifted, and so took her as his apprentice.
In some ways, Lambert was a great pater to her, as his focus on Mentem meant that she could focus on ghosts, which her magic seemed to have a natural affinity to, even as it sent shudders down his spine at times. But he taught her well, and when it came to spells dealing with ghosts, while he didn't know any, he acquired a tutor for her to learn from.
She also adopted some of his own failings, but she understands that it's not his fault, and has learned to live with it.
