In the depths of the lake, deep out of reach of any student, is a small cave closed by a large magical rock with a shell shaped hole in it. In that cave, a beautiful, fierce and regal mermaid, had been trapped by her brother. Arethusa was singing an eerie song that filled the small enclosure merely hoping against hope someone would hear her. Who would come to save her... who would resque her and return the magical key to restore her magic.
