The edgelord himself, bask in his evilness puny mortals. Well he isn’t as strong as he used to be ‘specially without his oh so special horn and well, they don’t grow back unfortunately. He’s currently hiding away in the glaciers and icecaves to where he was banished, waiting out til his time comes to attack though the thought has gone over him, why must he attack at this point, especially without his horn. Well that what his daughter was originally for, since Celestia and the other sisters believe he is dead, he was meant to use Dawn as his puppet. But he has never met her before and the sense of worry has become to slowly overtake him despite his obsessive and evil needs.
 
Maybe the time alone to reflect had sudden got some common sense into him.  
One day he’ll make it out and take action upon his new plan, or maybe… he’d ask for forgiveness for his crimes.
