A King with a Changed Heart

King Sombra, or more a different version of him from a RP I've been doing with a friend. A Sombra of the same story who was once a tyrannic king, but now is a kindhearted ruler. The castle behind him is his kingdom located in the Crystal Mountains of the frozen north. But how did this unicorn king change so easily...well let's just say that love, which he despised, is what saved him..
