This story is a sequel to Son of Shadows

While celebrating their victory over the Umbrum, a mysterious enemy from the distant past returns and makes a declaration of war. This enemy, long forgotten by Ponykind, wields a disturbing power that even the element-bearers cannot withstand. The task thus falls to Midnight Shard, Flurry Heart and the children of harmony to take up their parents' mantle.

After the Umbrum's defeat, Sombra and Radiant Hope set out to find the shards of Princess Amore, but the former King is still tormented by guilt. Along the way, he and Hope grow closer - even starting a family. Along the way, Sombra discovers that the journey of redemption is never easy, but that the destination makes it worth it.
