The Labyrinth

The Labyrinth was a network of lava tubes tunnels made of cold black basalt. There were some paths and bridges. Depending on who was describing it, the tunnels either spanned 100 miles north to south and more than 50 miles east to west, or 200 miles north to south and almost 100 mile east to west. Runes were carved into the tunnels to guide travelers, but few could read them. There were a number of rifts that cut through the Labyrinth, so many tunnels emptied into massive chasms or dead-ended. Some staircases have been carved into stone to overcome these chasms.
