Catriona Darja.
A mage's servant whose power relies on a person's perception of the world around them. She's virtually invisible to everyone that has no spiritual balance, so most if not all humans. Her powers revolve around Perception, and how any senses detect her. She can also warp memories and rewrite thoughts.

From time to time a person may see her, but it's more of an annoyance than anything else. She'll mess with their heads a bit, and be on her way.

Darja appears in her late teens, early twenties, but her real age is unknown.

Wanted for thieving of magics, kidnapping, and suspected of murder.

An actual villain, for either Everchange or Lonely Monsters. Haven't gotten that far yet.
