Sombra was an old fashioned king, one partial to jousting and tourneys and all sorts of flamboyant and altogether antiquated forms of enjoyment. His blissful time on the throne is interrupted as he is summoned to the war rooms of Canterlot Castle. He is asked a question he has been successfully avoiding for centuries. His refusal to obey Celestia's demands results in his kingdom's encasement in an impassable barrier.

He loses hope.

He loses his Kingdom.

He resorts to diabolical measures to retake his throne. Dragons abet him as he struggles with demons both in reality and in his mind.

He will stop at nothing to rectify these mistakes. He will go as far as coaling his own soul.
