Annis was a resident of Camelot and a customer of The Apothecary in Camelot. On one such occasion she purchased belladonna eye drops which caused her to see a hallucination of a goblin speaking while dancing in flames. She talked about her experience in front of Uther, and many bystanders. Her evidence helped Uther see that magic had in fact reached Camelot. However, her experience was proved to be a hallucination, when Merlin and Gwen found out about the eye drops (The Witchfinder).
