Chameleon

Nebula couldn't believe what she saw. It was a magnificent gravel-gray pegasus, with a striking yellow and orange-striped mane. Her eyes were a piercing light brown, and her cutie mark seemed to represent a circular calendar made of wood or copper, as if she were always on an mission transcending time and space.

"This can't be me!" you gasped. For the first time in your life, you felt full, you became something.

You weren't sure if this was thanks to this "Stellar." While he may have created you, he insisted that you had made yourself this magnificent, this stunning.

Stellar was strange, you said, now alone again. While you were crying and shouting at him, his voice remained calm, even a little saddened by the hate you had directed at him. He genuinely sounded sorry for not being able to give you the best, and he seemed to have conflicts of his own.

Even stranger, he introduced himself as Stellar and Stargazer. Maybe the second one was just a pseudonym, but why would he want to hide his real identity, and why would he reveal it to you? You tried to put everything in place, but were still lost if between sympathizing with that odd character or just ignoring him.

"That's a good way to resume him," another voice echoed through the empty and vast world around you. This time it was more feminine and a little less calm and compassionate.

"Who are you?" you asked, a little startled by the appearance of a second voice.

"I go by Colibri, but that's just a codename!" answered the voice quickly. "When I found myself lost in Stargazer's world, he raised me like an apprentice, and now I'm helping him cut ties with a secret agency that doesn't really like him."

This was... strange to say the least. For most of your life, you felt alone, empty, and now you met your creator, found your true self, and had been faced with so many revelations you thought you might explode from processing errors.

"Anyway, Stargazer is gone now, and I need to finish something before leaving. He told me to paste this into your storybook once he was gone."

As the voice pronounced her words, the world shifted. The empty walls and floor started to colorize as the sky seemed itself incrusted in stars, the sun, and the moon. The place you were standing on became a cliff, and an enormous observatory was building itself on the side, half of it hovering above the void that was slowly becoming an endless sea.

The building itself was magnificent, arranged in all the colors of the rainbows. A tower stood tall, ending in a dome with a telescope. The side of the tower was arranged like the home of a fisherman or a lighthouse keeper. On the side, above the sea and supported by two magnificent fir pillars, was a gigantic open-air library, filled with books of all colors.

"You see, Nebula, Stargazer wanted you to become the worlds-keeper. Each of those books is the story of a creature on a world, some are true worlds, some are fake, but each of them feels real to the ones who are in them. The telescope on top of the tower is a lens towards those worlds, allowing you to see what the characters feel. It took him almost a decade of story writing, proofreading, and research to end up with it working. You were his biggest project, Nebula. He started to make you before I was even here!"

This was a lot to take in for you, and as you approached the building, you could see a sign placed on the wall, with "For Nebula" written on it.

You started to understand what he meant by "you can write your story yourself." You were now the keeper, the guardian of all those worlds. You were made for that. But destiny wasn't already written, and this didn't seem to be the worst life ever. The place was nice, you had infinite stories, and just needed to guard this knowledge. Maybe that's what your cutie mark was for, this forever time-watcher you became, an eternal companion for an eternal guardian
