Aoife grew jealous of the children's love for each other and their father so she plotted to get rid of the children. On a journey with the children to Bodb's house, she ordered her servant to kill them but they refused. In anger, she was about to do it herself, but didn't have the courage, instead she used her magic to turn them all into swans. As swans, the children had to spend 300 years on Lough Derravaragh, a lake near their father's castle, 300 years in the Sea of Moyle , 300 years on the Isle of Glora. It has been suggested that the site of Lear's castle is currently occupied by Tullynally castle, home of the Earl of Longford, as the name Tullynally is the anglicised form of tullach an allach or "hill of the swan". When Bodb heard of this, he transformed Aoife into an air demon for eternity. While they were swans, St. Patrick came and converted Ireland to Christianity.
