lce Witches are minor characters in the Di'angelo series. However, they were only mentioned in the Di'angelo and Aza episode Sicily. They were never seen and not much is known about them. Sicily obviously has some negative history with them because of Thomas's scolding of "Sicily, what did I tell you about messing with those Ice Witches?". Otherwise than that sentence there, the Ice Witches have not been mentioned or shown in the series. It is still possible for them to appear in a future episode.
