Princess Luna is a character from My Little Pony: Friendship Is Magic, which premiered in 2010, where she rules Equestria alongside Princess Celestia and is associated with the night. Short fan-shared greeting clips like this circulated in the brony fandom, where holiday voice lines are remixed into edits, messages and seasonal compilations. A Christmas wish in Luna's voice fits the fandom tradition of making character greetings for special occasions. It remains popular because it is instantly recognizable, very short, and easy to reuse every December.
