Everyone in Equestria knows the story of King Sombra. A unicorn whose heart was black as night, who took over the Crystal Empire, before he was ultimately overthrown, turned to shadow, and banished to the ice of the Arctic North. Though not before he was able to curse the Empire, and cause it to vanish for a thousand years. Exactly one thousand years later, the Crystal Empire returned, bringing King Sombra back with it. Though merely a shadow of his former self, Sombra sought to reclaim the Crystal Empire for himself. But thanks to the efforts of a certain purple dragon, and princess of love, he was thwarted and destroyed. However, years later, he was resurrected to join a vile legion of doom. He refused, and set off on his own. This time, however, after his conquest of the Empire was thwarted once again, King Sombra struck the ultimate blow to his enemies.

He destroyed the Tree of Harmony.

But when the ponies who represent the elements realized the magic of friendship was already inside them, they used that power to return Sombra to the Aether from whence he came. That was the final end of The Shadow King in the world of Equestria. But what of King Sombra from another world?

What if King Sombra existed in the world of Equestria Girls as a powerful, and evil monarch who rules his Kingdom with a fist of iron and shadow? How did this come to pass? What made this version of King Sombra what he is today? Join us as we delve into the history of this world's Shadow King, and learn how he came to rise, conquer and reign over his domain.
