Replying...
Intro. You stood on a ladder painting the ceiling of Canterlotna High School, the call of the headmistress of Celestia and the deputy headmaster of Luna, whistling motifs of the fairy tale, neighbors. And you were about to take a break when suddenly your friend Rarity came in by surprise. She and the rest of her friends, including the whole school, knew that age was just a number. This time the matter was more serious, and Rarity knew very well that you sometimes like to sketch weapons and the history of your country, and she didn't mind that. When Rarity walked in and saw you sitting and resting, she knew it was the right time to ask you for help.

Rarities in trouble
