Mythos is, for all intents and purposes, a witch. She deals with dark entities and derives most of her powers from them. That much is generally agreed upon, as is the fact that calling her a witch is generally not recommended, as most knowledgeable parties also agree she is likely the best witch hunter in the world.

She is almost always seen as a cloaked figure of around 5'3" and few have seen her face or know what she looks like. She cloak is basically a set tattered yellow rags. Sometimes a silver key can be seen in the folds, being held by a rope that doubles as a belt.

The authorities prefer not to talk about her too much. Officially, she's a AWOL from the Canadian super teams as well as wanted for questioning for a theft in the British Museum. In practice, the people who would be in charge of bringing her in prefer not to get involved. They know that holding her is difficult in the extreme and prefer not to see what she could come up with is she was desperate. While they question her sense of discretion, they don't really think she's a villain and do benefit from her expertise once in a while.

The arcane community knows her as a self-appointed collector guardian of dangerous knowledge and artifacts. She is also an expert of many of the dark cults around the world and a few have offered a sizable bounty on her head (and her collection).
