King Sombra isn't totally destroyed by the Mane Six's blast in Canterlot, but he's banished back to the Frozen North and is severely weakened. Determined to take revenge, he's eventually imprisoned by Princess Celestia and has a choice to make: reform himself to use his magic for good, or be turned to stone.
Takes place during Season 9, just after Sombra's defeat. Also assumes you've seen Season 9 so beware of spoilers!
