|Her eyes were blue, not black. And she had freckles - on her nose, her neckline, her shoulders. They weren't unattractive, they suited her complexion and reddish hair.|

Iola joined the Temple of Melitele and pledged herself to the goddess by taking vows of silence, which remained unbroken. She studied under Nenneke, learning healing skills and magic, and was considered quite bright in the older priestess' eyes.
After Geralt of Rivia was injured in a fight and came to the temple to recover, Iola cared for him, which eventually led to a relationship between them, and them sleeping together. Later, Nenneke walked into the room and asked Iola to leave, as she believed the relationship was not appropriate, considering it would distract her from her duties, even though it was Nenneke herself that had sent Iola to Geralt's room to calm him down.
Later Geralt told Iola about his life as a witcher, explaining his training and monsters he had fought, and as he explained she showed interest in his swords, nearly cutting herself, and worried he was upset, trying to comfort him. Later, as Geralt was leaving the temple, Iola brought out his chest of elixirs and gave them to him and as their hands touched, Iola suffered a seizure and was carried off by pupils to be treated by Nenneke later.
- In The Hexer TV series, it varies from the books in that Iola broke her vows of silence and she foretold the deaths of Falwick, Renfri, and the priestesses of Melitele in the temple, including her own.
