This story is a sequel to Dark Matter

The final story of the Savage Skies series.

The world has been saved and the years have passed. But for Dawn Lightwing, not every challenge is behind him. He finds himself faced with something possibly even more difficult than a murderous cult or a mad scientist performing a world-ending experiment, finding what it is that he truly wishes to do with his life. Both Dawn and Scootaloo will go through experiences that challenge their desires for the future and their relationship with each other as they navigate along the final stretch of the convoluted path to adulthood.

Everypony has a story. Some tell of heroic feats and grand adventure. Others tell of villainy against the forces of Harmony. The story of an average guard, however, is one of obscurity. They live in the background, unnoticed but ever-present.

Silent Knight assumed his tale would be like that of his father's: join the Royal Guard and serve Equestria. He would be just another helmet and spear, part of the rank and file. And that was all he ever wanted.

However, when Captain Shining Armor asked for volunteers to form a House Guard for the recently returned Princess Luna, it was Silent's hooves that stepped forwards to set his new life in motion.

Oriole has a problem. She can't stop eating stallions.

Rarity has a problem. Her new friend can't stop eating stallions.

Twilight Sparkle has a problem. A stallion-eating monster has moved into her town.

Spike's just glad he's not a stallion.
