This is an excellent rendition of King Sombra. I've gotta admit, I was curious to see what version of him we were going to be introduced to when the mention of mirrors was brought up; but now that I know a little more about the coming arc, I know only 3 things for certain:



1) Star Swirl the Bearded was kind of a jerk, despite his legitimate concerns about the two worlds colliding.



2) A noble King Sombra?? I'm still trying to wrap my head around that one; I don't think I'll ever see him quite the same way again! Especially if his connections to Celestia Prime are what I THINK they are...



3) Mirror Celestia is evil? Then I can only assume that the writers have finally found a way to play with the Tyrantlestia meme without stepping on canon toes. XD
