The fisherman certainly isn't a famous hero, who saves the world in the last moment. I wanted this story to be about one "insignificant" person, instead of big political/interstellar/space ship thing. Instead of cold description of planetary catastrophe, I decided to show it from a limited perspective of someone who experiences it first hand...and how it's remembered 500 years later.
I'm glad that the idea worked
