There are places in a citymech that most fear to tread. Places where the machinery that makes a mech function leaves little room for squishy things like you and I. These places are called the Gearforests, and they are far from lifeless. Rats, snakes, lizards and other creatures have taken up residence. The decendents of halflings, sent in there a century ago to service and maintain the machines, now guard it as their tribal homeland. Its a nasty, hot, smelly, sticky environment. Naturally adventurers seem drawn to them.
