Writing ancient scripts on the rock walls, recording life, is not the act of a single person but of a group of people.
This group consists of homeless exiles.
These travellers record the various events of the migration period on the rock walls. They board vessels to escape the apocalypse, fleeing to the unknown south, hoping to see the sun of the oasis.
Many died during the Great Migration... The fleet was often attacked by storms, and the number of survivors dwindled.
No one knew what their future would be like.
Would they succeed in finding the "oasis?" Or... would they be swept away by the storm, then perish?
Yet these "travellers" could never have imagined that their ultimate fate would be a third option.
Abandoned by their people.
Cast out as abandoned children, left in the [Old World].
