The Gaurdians

There was once a king who divided his kingdom between his four daughters. The four princesses defended their kingdom in the dark war against the shadow warriors, and won triumphantly. Although, a war cannot be won without sacrifice, the youngest daughter, Elinor the wise, was killed in battle. Their world was brought into utter despair. The Guardians continued for generations, but the wise guardian always died first. In 1997, Alley the wise went dark and corrupted the next in line.
