Murals

The mural's depiction of that messenger was extremely simple, just a few sparse strokes.

Compared to the other exquisite details, the messenger's image looked terribly rough, and every appearance was completely different.

Sometimes it resembled a tangled mess of randomly drawn lines; sometimes it was a simple triangle or circle. Placed among the mural's finely crafted details, it seemed utterly out of place.

It seemed the craftsmen who created this mural had not wanted to waste much effort on the messenger. Or perhaps they had deliberately made its image so careless to express their contempt for it.

Yet the mural depicted those traitors after their mutation with great care. Stripped of their fur, they were bare and hairless, their bodies even more hunched over. They looked like tailless rats curled into balls, with hugely swollen bellies. They also had no heads, making them appear quite bizarre.

The mural especially emphasized these traitors' fear of the darkness, devoting an entire section to their helplessness within it:

The messenger sent them into the darkness to search for their original people, but they did not dare go. Nor did they dare defy the messenger's orders, so they could only huddle together and creep forward timidly.

All kinds of dangers surrounded them, yet they remained completely unaware, fearfully pointing their crude weapons in every direction, having entirely lost their original ability to adapt to the darkness...

The mural did not seem to describe why the messenger had spread the mutation. It only described what it had done and the immense harm its methods had brought upon the race.

At the end of the mural, one group of the race scattered throughout the darkness built pyramids and recorded their people's experiences upon these walls.

As for the other groups, there was no way to know...
