Hostages of the sun

The world in which the sun"s rays became deadly.
The world in which the children ceased to be born.
The world in which each village is an autonomous state with its power and its own laws.
The strongest survives here. Here is the one who shoots first.
Your peers grew up, considering stories about the old world stupid fairy tales. Not all of them know how to read and write.
You are the weakest among them, but the strongest among those who survived, clinging to the dying technologies of the past.
You are not able to keep a weapon brought up on the ideals of humanism, who did not know either pain or betrayal. The last hope of those who survived.
Your path begins here and now.
Your duty is to get to the goal
