Equestria is as most pony's know it all but gone. King Sombra and his Queen rule with an iron hoof.
Five mares and one Draconequus spend their time in a dark prison cell. Until one day they are visited by someone Discord never wanted expected to ever see again.
His older Brother.
Inspired by the fantastic Lost into Shadow. and its Sequel.

King Sombra survived his defeat, but just. By the time he returned to form, Twilight became the newest princess of Equestria and the Crystal Empire was restored to its former glory.

He cannot take over Equestria the same way he tried before, but he has a card up his sleeve. Twilight won't see it coming, and Sombra might gain a powerful ally in the process.

And it will all begin...with a book.
