Granted. A moony maiden falls from the sky, after slipping on an ancient Lovecraftian banana peel, due to the much lower gravity.
Unfortunately for us, she's actually just a Moon tourist, and the only member of her civilization to be within our deep solar system.
The fall damage caused her to lose a lot of stamina, and also ripped her skirt wide open.
She now has to relearn her obscure gliding technique from ancient warrior Dondo Li: The Art of Holding S.
After several sidequests, she's finally ready for action, and reaches a space elevator. To everyone's surprise, the elevator was actually coming down, and none other than the Space Egyptians come out of it!
Before they are able to start the fight, the Moony Maiden finally drops her terrifying bombshell:
"Sorry pals, but the Moon ain't maid of green cheese."
Shocked by the revelation, they go back to the Mothership and tell everyone, including the Emperor.
Their sentient unobtainium batteries collectively have a stroke while trying to process the information. This causes the main reactor to malfunction, and the Mothership plummets to Earth and hits the Jupiter Moon Martians HQ.
After realizing the great Empire of Space Egypt has finally come to an end (for the fourth time...), one of the remaining invaders actually congratulates to the Moony Maiden and asks her to become their new leader.
She kicks the Jupiter Moon Martian in the nuts.
...However, due to the butterfly effect, some unknown planet is destroyed 100 billion years earlier than expected, and that causes countless vampire squid humanoids to unwillingly invade Earth...
I wish someone would take care of them.
