A demon in the nether (what we would call it Heck ruled by Satin aka Devil) found a nether portal created by a player. This player of course was long sense gone but the portal he had forgotten to take down. This demon wandering quite what it was traveled into it. This demon found a Enderman in the real world, wandering what it was he studied it curiously. Of course being a Enderman this creature got very angry at the demon staring at it, as they do not take a liking at being stared at. This Enderman attacked viciously. The demon won of course knowing that it is from the nether (again aka Heck) I would guess it would be a minion of the Devil, witch would have to be strong to work under such a powerful being. This creature although was not unscathed after the fight. The demon had been bitten by the Enderman. This created an infection, that spread through the top half of his body. He was turning into a Enderman! But his pure will to live, fought off the infection, but there was a downfall. Part of his body had been turned into the Enderman already. He was half Enderman half Demon. He created a new hybrid witch multiplied in population. Now this new hybrid is as common of a being as all the others. You are one of these hybrids.
