Excellent and short fiction story. But I felt there was big meaning behind your writing. Lot of destruction came via humans bad activities. But bad things did only few peoples. Unfortunate thing is result available for whole community. I think you try to mean like my idea. If I''m wrong please correct me.
The idea is to leave an ending that can be interpreted in many ways so that the most imaginators can create its continuation. I love it like that. And the story is about a kind of macroscopic plague that was born from the planet itself in its beginnings as one of the possible defense systems, the purpose of which is to create a restart.
