Chero is commonly known as the "underground city". It consists of many tunnels that lie beneath the city. It is a dark place, lit up only by candlelight. Here humanity waits in hiding, surviving but not really living.
It is here that The Renegades live. Led by Zara, they are around to help people move away from the dangers of the Demons and to save those who are enslaved. On the rare occasion, the Rebels will come to Chero, though their leader Andy does not like being underground so these times are rather short lived.
Houses here are carved into large rocks in buried in the ground. There are small shops where people can trade food for other things they made need. Jobs here include hunting, candemaking and scavenging. It is a pitiful existence, yes, but still far better than what awaits the people living in Abaddon.
There are some who live close enough to the city that can work in the city - usually in the entertainment district. These people are often not well-liked among those living in Chero as it can risk them being caught.
There is only one way in and out of Chero, and that is through the drains of the streets. Once entering the sewage drains, there are small tunnels that lead down into the tunnels.
