Synopsis: Those players think that I am one of them

I am the Dark Lord, the one who united the demons, someone with infinite power. I am sick of it all, and these people have attacked our lands again. For the past hundred years, vile players have been attacking our hellish lands, mercilessly plundering and killing peaceful demons. Today, I will become human and sneak into their ranks to destroy their rotten system from within. They will think I am one of them, but I will bring their world to its knees.
