The Crown of the Crystal Rose
The Land of Vox is a tranquil state that many enjoy. For the most part all people and races coexist without issues. The only time things ever really get heated is when the King dies. In Vox, when a King dies, his successor is not of his bloodline, usually. The next King is decided by the previous King before he dies. In order to be king, you must be someone of exceptional skill, whether it be your skill on the battlefield, your economic prowess, your tactical abilities, your dicploacy, etc. You must be the top performer in that category.
Before they take the throne, every king-elect muct go on a journey of self-discovery. There they hone their skills and acquire a relic. A relic is a magical item that is tied to a specific king. Relics, when in the hand of their specific king, can increase their lifespan by 100s of years as well as make them better at what they do. Each king is buried with their relic when they pass. Some relics lose all their magical ability when their respective king passes, some hold on to some of their power, very few retain all of their magical power.
