The Caverns are inside the Tørstår Rift. There are many thousands of caverns connected to each-other and the Rift. They can be accessed from any part of the Rift and only the most knowledgeable Tørstårians can navigate them. The poor and criminals typically live deep within the caverns, most people refuse to go into them without some protective measures. There are some well paved caverns used as a type of road between Rift Towns, these typically have less crime, and are relatively safe to travel.
