This entity never knew what happened to it.
It only knew that it survived, devoured, and evolved, until one day it became unbeatable.
Yet… somehow, even though it had worked so hard to thrive, survive, reproduce, and become the strongest, it was one day trapped into a strange space.
Forced against its own will to remain in a single place, as if time has stopped, it could only grow in anger as all the efforts it had exerted through its long life were gone, no matter how hard it tried, no matter how much work it put… it was possible, it was locked in a single place.
I hatched from an egg hundreds of years in the past, within the depths of the lake of poison.
As it was small, it could barely do much other than hiding from the immense predators roaming at every corner.
It was a tough life.
However, it continued to slowly rise through the hierarchy and food chain.
