Long ago, before space and time existed.
More precisely, before all history, concepts, plots, information, and abstractions existed.
There was a dragon named Selena.
No one knew where she came from. Simply because she didn't exist in the past or the future.
She wasn't bound by normal causality, because she created that kind of cause and effect.
To put it more accurately, she didn't exist.
No physical body, no soul, no mind, no concepts, no plot, no history, no information. Even the void wasn't as "empty" as she was.
Another version of her existed in a lower dimension, in the "Observable Universe."
That version lived in the Earth's core.
And then, everything happened as she had planned.
Everything in 3D space is just a comic book within another comic book, to her.
4D space is just an ordinary dream to her.
They say that when she wakes up, the entire 4D space will be instantly erased. The 5D space will also collapse.
Yet, somewhere, there are still people who want to wake her up.
