Midnight Blossom and Cloud Skipper

Midnight Blossom and Cloud Skipper are two Royal Guard ponies often seen in fan art together. They also share roles in fan fictions such as A Tryst at Midnight, A night at the Shady Trough, and Her Destiny. These two characters are presumably what inspired Comet Burst in writing The Golden Armor.

Midnight Blossom
The vivacious female member of Luna's fierce royal guard.
