Lurue

Lurue was an Archfey who ruled over the talking beasts of the Feywild, especially unicorns. Her face bore a single horn, and her beauty was unparalleled even by the high standards of the Feywild. She spent most of her days exploring and adventuring, in search of true love.
On one such day, she was wandering the woods and met another Archfey known as The Prince of Fools . The two immediately fell in love, and were married within the week. They lived together for over a decade, but then had some sort of falling out. The exact cause of the disagreement is now lost to history, however their arguing quickly escalated, and their followers began to fight each other throughout the Feywild. This conflict became known as the Lover's War, and lasted for only a few months before Lurue was slain in battle.
