She appears as a woman in her forties, with short blonde hair and green eyes. She lives in San Francisco, as the proprietor of an old wood-made house. She works as a professor of Medieval Studies at a university of the city she lives in, so she can use her vast knowledge to teach her students about what she has seen and gain a considerable amount of money.

Personality
She has a mysterious, but seems to be kind. She cares about her belongings, and actually worries about what could to anything valuable she has--like the time when Dean used explosives to take out the Sword Of Bruncvik within the rock in her basement floor.

She has deep and vast knowledge about creatures and, more likely, anything that has to do with the Medieval Age. However, she does not seem to be egoistic when it comes to share or give information, if treated appropiately and if she has her own motivations--such as being able to stay in Earth. Speaking confident about her own knowledge, she gives the exact information needed without complaining.

Story
Having lived for more than 900 years, she has gone through a lot. However, she only appear little time on the series, and not much background story information is given, except for the fact that she was involved romatically with Bobby Singer.

Season 6
In "Like a Virgin", Dean goes to her at Bobby's advice to find information on dragons and how to kill them. She possesses a sword capable of killing dragons, the Sword of Brunswick, which is stuck in a large rock in her basement. Dean blows up the rock using explosives, breaking the sword in the process.

In "Let It Bleed", Bobby finds out that she is in fact a creature from purgatory. She tells Bobby that she is 900 years old. The body she inhabits is the maid at H.P. Lovecraft's party the night they opened the doors. When Bobby tracks her down, he warns her that Castiel is probably right behind him. Bobby asks her to let him protect her. She refuses and tells Bobby she can protect herself. But as she is leaving, Castiel appears behind her and grabs her.

When she disappeared, Sam, Dean and Bobby go look for her in "The Man Who Knew Too Much". They find her and she reveals that she told Castiel how to open the door. Bobby asks her how to open it and she replies it is needed blood of a virgin and blood of a creature from Purgatory. Then, she dies.

Dr. Visyak possesses a vast knowledge of the supernatural and the know how to kill creatures. It's possible that she has superhuman strength and agility because of how she mudered the horror writer H.P. Lovecraft with great force.
