After the failed assault on Canterlot, Chrysalis's changelings abandon her. She knows the other changeling hives won't accept her, not after her pride. She is forced to go to Canterlot, where a certain Mare of the Night finds her.

Luna is depressed. Celestia insensitively brings up Nightmare Moon while Cadence leaves for the Crystal Empire. When she encounters a new bug-like mare, she confronts her sister, encouraged by her new bug friend.

This is a tale of the Moon, of Bugs and of the Sun. But most importantly it's about family, friendship and love. It's a tale Of Insects and Moons.
