Time Turner returned on Hearth's Warming Eve. After his six month disappearance with no memory of what happened other than the belief he fixed something, he was finally reunited with his family. However, things that were meant to be forgotten have a way of creeping up on him as the mysterious death of a Royal Guard and sightings of creatures make headlines in Equestria. Before long the creatures go from lurking to actively making appearances, bringing havoc with them. In the midst of all this, the Doctor begins to realize that this is linked to his six-month disappearance.

A kinda-sorta sequel to All These Lights.
