Eerie Island is a wizarding prison in the United States, possibly located in or near Lake Erie.
Quick later mentioned the prison to Diana Grimm in early January 2010, and to her friends in September 2010. In October 2010, Albo called sixth-grader Mary Dearborn a "little bitch" who deserved to be sent to the prison after she cursed him and his familiar.
