Society has dreamed of other worlds far away on other planets. It is not well known there are millions daily, right here on our own.
In each dew drop there is a world. Some like ours, some would be unrecognizable to the average person. Each different world meets an untimely fate when the dewdrop that it lives in is destroyed.
There are many different ways for them to be destroyed, each with it's on level of pain for the citizens of that world. When a finger pops a dew drop the people of that world will be crushed and will feel a blinding pain before they die. When a dew drop evaporates it is painless for the creatures of that world because it happens so slowly. There are many more ways but they are for you to find, not for me to tell.
