An astriod landed on earth and wiped out the whole population. Everything was burnt and collapsed. The whole world took a literal dark turn. There was no more sunny days. Everything was ruin down and dreary. Everything seemed to have a yellowish tint to it.

the guy puts his hands up

"Woah, woah, I'm not gonna hurt you."
