Is Mordekaiser an ancient Shadow Isles. king?

I was thinking about champion names, then I came to Mordekaiser () , breaking it down to Mordecai and Kaiser. Kaiser was given to emperors of the German empire, thus the theory. Going further, I came up with the following extension: he was a very corrupt king, and upon his death, he was buried in a suit of armor in a way that would have offended him in life. A wraith from one of the other graves had felt the negative energies from the newly dead king and suit of armor. The wraith had gotten enough energy to physically bind itself to the armor, and after enough time, was able to roam the Shadow Isles. once again.

If you have any problems, or want to add only in any way, feel free to do so, I only request is that you give me credit for the original thread.
