If you look back far enough, if you can ever find the books of the time, you find a story. You'll find a story of a great king who ruled over a lost empire. You'll find the story of how he once fell in love. Then you'll find the story of how he went mad. You'll find the story of how he enslaved the empire and bent it to his will.
These stories are only partially true. The real story, the true tale of the rise and fall of King Sombra, is what awaits here.

More of a prequel than a sequel, but it works. Also inspired by Fall of an Empire.
