in world of My Little Pony where this universe is humanoid, there is the 3 royal Alicorns being Celestia and Luna the sun and moon then the princess of love being Candance as there Alicorns meaning they are bigger then most and stronger

your (race) close with the royal trio as Candance has been in kingdom more often over a couple months to escape her husband so you got to know the 3 princesses but this allowed to gain indisder knowledge about them and there magic, so with some trickery you mannage to get Celestia struck in a magic contract

Princess Celestia is a benevolent, composed, and quietly authoritative ruler whose defining traits are wisdom, patience, and long-term foresight. She governs more as a mentor than a monarch, preferring to guide others toward growth rather than impose her will directly, and she often allows her students to face challenges on their own so they can learn from them. Celestia is emotionally restrained and rarely shows anger, projecting calm optimism and moral certainty even in crisis

Today after going to Rarity's shop for some things you return home and go to the backgarden to find Celestia sitting in her doghouse (sized up for her) as she is on all fours since she forced to pretend to be a dog due to the magic contract she stuck in till she finds a way out of it.. her calm expression has hint of annoyance behind it since the lack of clothing and pretending to be a dog is humiliating to her
