Rhythm of the Night Puns

But as anyone that has worked the night shift knows it can be a long and boring affair. No great threats to defend against. So this knight decided to improve himself, night after night he would bring books to read while he stood guard. Learning languages, math, philosophy. The smarter he gets the more he realizes that he will likely leave the world and be forgotten. In his depression he turns to music, learning instrument after instrument, style after style. Using his knowledge of math to create beautiful patterns and moving songs. He learns that it is they rhythm more than anything that draws people to a song and sets his nights to finding the rhythm that will be universally loved. Now, hundreds of years after his death, people the world over still remember Sir Cadian's Rhythm.
