Rivers full of Rubble

The third entry in The Valley is the World, an oversized 24XL TTRPG! 

When the party gets close to Passo they see the tent city. Their friend Yoji is cooking in a makeshift kitchen, and tells them what's happening. The Blue's and the Greens have divided the city up for years, but recently their antagonism has curdled into bloodshed. The majority of the people, without affiliation, are struggling or leaving. While this situation persists, your party cannot move through. 

Embody the man with no name, draw their violence against each other and make the city safe again.
