In one of the futures where Starlight Glimmer interfered with the past, Twilight was sent to a future where king Sombra ruled the Crystal empire and waged war with Celestia and her kingdom.

Twilight heard what happened to her friends, but she never did ask what happen to herself in this timeline.

In this future, The Twilight of this timeline still had a passion for magic but lacked any talent to use it and lived an average life never knowing her true destiny.

Fate still has plans for her, although it involves becoming a slave to Sombra.

She believed she would be broken by him, but he had other plans.
