This is part of the Ravaged World continuity.
"The Weird Event That Changed John's View" is a legend passed down through countless generations and a key part of the Cult of Aacqua-Yei's faith.
When men become boys, and bullets are dodged.
When the dead walk the earth, and the noon is high.
When masks are riven by fire, and squids are trampled once the yee finds its haw.
The World-eater wakes, to be raped by the last great ogre.
