Vaati Double Agent

Losing the cap was one thing, having someone else use it for evil purposes was another.Now Vaati finds himself as the personal right hand of the king of all demons while the princess of the land requests he makes sure the hero sucesfully goes through his journey. A rather hard thing to do when his mentor eagerly believes he was evil all along and has made sure to share that opinion with the hero on whose head he lies. Now he has to play both the hero and the villain without either realizing his charade.Because if they do, he would lose all control in the situation. And he really wants an ending in which he doesn't get executed by good or evil.
