 The original four sisters were women who lived on an island west of Deltora's coast and had voices as sweet, as their hearts were pure.Their names were Flora, Viva, Aqua and Terra and had lived on the island for so long, they had forgotten the number of years.A sorcerer (confirmed to be the Shadow Lord in Tales of Deltora) came sailing from far away, looking for lands to conquer, heard their songs and despised them because he hated all things beautiful and good.
