In the aftermath of the Storm King's power play, Tempest Shadow finds herself at a crossroads once again. She hasn't been banished, but no party can change the festering feeling of being out of place. Exploring the caves underneath Canterlot, she stumbles upon an odd, crimson shard, and a spirit of a lost king who promises to mend her broken horn—and while he's at it, to help her get her old life back.

The hornless pony finds the ponyless horn's offer tempting.
