Eighth Ark had enough cryogenic pods for all of them, and there would be enough room for twice as much. Alea sealed the ship, programmed its system for the closest target in database and let it fly. Where it would end, where would tides of the universe carry it, no one knew for sure. Twilight's friends took the remaining Elements of Harmony with them, along with broken Twilight's crown. They would serve as an reminder of this event.
My sisters and I took the roles of ruling Equestria. Luna would join us in time, once she would cope with her own sister's illness.
Celestia didn't die, and death would be fulfilled wish for her. When Twilight touched her with dark magic, Celestia's powers got corrupted as well. Unlike Twilight, she didn't go mad. She was slowly loosing her power to the point standing up was a problem. One day, she wouldn't wake up at all.
After that, Luna would become a fully fledged Queen of all Equestria. It would be hard, but I was sure she could do it. She had me, and my sisters.
For the ponies of Equestria, getting from the grasp of enchanted regalia, it was like waking up from a dream. Real problems were suddenly a thing. It wasn't just sunshine and rainbows anymore.
One last ceremony was held, for the fallen heroes. In the name of Shining Armour, Princess Cadence, Princess Celestia, Queen Amora, Stardust, and many others, that died on the way.
I forgot to mention, Thorax disappeared. I asked my sisters how did he got outside of our ship, and by their words, it was him, who let Celestia out. Where he had ended up was a mystery, but to be honest, I didn't feel like looking for him.
New adventures were in our grasp, and the age of advancement, where ponies and changelings would work together, was finally here.
