King Sombra was a cruel tyrant who ruled the Crystal Empire 1000 years prior to the setting of the show. He was described as having a heart as black as shadow, and was capable of using an unusual form of dark magic. He was overthrown through the joint efforts of Princess Celestia and Princess Luna, who turned him into a living shadow and imprisoned him in the tundra. However, he was able to curse the Crystal Empire as a last act of defiance, causing it to disappear for the next millenium.
Upon the empire's return, it was shown that he had placed a lingering amnesia spell that prevent the crystal ponies from any part of their lives before his rule. He had also destroyed information about how he could be defeated and placed numerous traps as deterrent, including a door that led to the greatest fears of the one who opened it. While Twilight Sparkle attempted to find the Crystal Heart necessary to defeat him, Sombra attempted to attack the Empire in his shadow form, forcing Princess Cadance to constantly maintain a barrier to keep him out. King Sombra was eventually defeated for good when the Crystal Heart was found and the citizens were roused to use the light and love inside their hearts to destroy him.
