Lord of Boredom

Imagine you're the most powerful existence in the whole universe - You can do literally everything! However after thousands of years of existence, you are getting bored. You experienced anything that could be experienced, you lived through eras and meet millions of existences, you did everything that could've been done. You are more knowledgeable than anyone have ever been. That's what happened to a god called Xander, atleast that's how he calls himself now, until he gets bored of this name.
