The tree elves were originally the masters of this galaxy, until one day, a civilization from outside the galaxy invaded. Inorganic matter collides violently with life, peaceful life is broken, and millions of years of tradition are overturned. Homes were destroyed, countries were outlawed, and people were enslaved. The story takes place on a very inconspicuous edge planet, it is just an "ordinary person", an old man, and an opportunity.
