Queen Serenity lost her shit because her child, the only other person who could possibly understand her and the responsibilities on her shoulders
she's basically the High Priestess of the Silver Crystal and all that's keeping it from wrecking every shit in existence
she somehow creates a child who's her near clone and will inherit this enormous duty
outfits her with personal security and a governess/tutor/familiar/pet
you know Luna and Artemis had to come from good families with a reputation for both professionalism and forming tight bonded with their charge
and she's a child, she hasn't been around for 1000+ years and fought off fuck knows what
I forgot, Queen Serenity also was responsible for a door that led into the 4th Dimension, and supposed to watch over the Earth
the same Earth that her daughter started sneaking off to
kid managed to survive on Earth, fell in love with the prince of Earth
some pagan girl with the hots for the prince makes a pact with a sentient solar flare
annnnnnd proceeds to start a war against the kingdom protecting them all from Things That Should Not Be
if memory serves me right, the princess died on Earth, so Queen Serenity probably didn't get to hold her or anything
what if she was so distraught that instead of unleashing a massive attack on the possessed Earthlings she accidentally sent all the power to the dead princess on Earth
and anything she had left, she used to seal Metallia away, arrange reincarnations, and instruct Luna.
and make a tiny hologram of herself
