Opaline grew up being bullied and unseen by the royal sisters, whom she tried tirelessly but unsuccessfully to impress; still, Luna showed her more kindness than Celestia ever did.

Alone and friendless, Opaline fled Skyros and found safety in Canterlot, where she stayed until Nightmare Moon’s banishment. After Celestia imprisons Luna in the moon, Opaline confronts the ruler of the sun, forcing Celestia to come to terms with the role she played in Luna’s downfall.
