Several years has passed, They've died after the "blood moon" due to their weak body and illness.

[Author here, As you can see this is a parallel world of the Earth itself and is inspired by the Bible, But *spoiler alert* it's not the story of the Bible itself, I just used it as a reference of explaining the beginning. Also take note that I sorta suck at grammars]
