Physic/Livvy is the physician of the Black Swan. In Book 6: Nightfall, she is revealed to be Livvy, Quinlin Sonden's wife. She and Quinlin have an super unstable relationship, fighting often. They show signs of such in front of Sophie, Amy, and Sophie's friends in Nightfall. Livvy apparently was supposed to file a match fail, the elves' version of a divorce, but hasn't, so they're still considered to be married.
Physic was the person who helped Fitz Vacker after he was impaled in Exile (Book 4: Neverseen). It was said that Physic was in the Collective until she made a mistake, so she gave her place to Juline Dizznee, as she was her doctor. It is said that the reason she gave up on being the Collective is so that she could focus more on medicine. This is because Sophie Foster had an accident in the Forbidden Cities with limbium, something Sophie is allergic to. The story doesn't go into detail about the topic, but it had something to do with Mr. Forkle and Physic.
In Nightfall, we learn that Physic is really Livvy Sonden, Quinlin's "ex-wife," but not officialy, because they haven't filled out the divorce papers, also known as a Match-Fail paper, because of the shame that it would bring. We also learn that she once took a trip to the Forbidden Cities using Quinlin's pathfinder to learn more about humans, and their medicine.
When working for the Black Swan, Physic frequently wears a Mardi-Gras-style mask to conceal her appearance.
She has dark skin, tiny, sparkly jewels woven into her hair, full lips, and a softly rounded nose.
One of Physic's masks is Mardi-Gras-style and red, with a rim of gold glitter. She has also been known to wear a purple mask decorated with black swans.
