A large, inactive volcano and current headquarters of the resistance.
In the Age of Old dwarves created vast mining tunnels inside and below the mountains. These mines had been abandoned for centuries when the resistance chose the mountain as their home and created an impenetrable fortress on the side.
Walls of cobblestone tower along the sides of cliffs, covering a defensive stronghold within. Below the surface their are expertly carved and spacious mines which the resistance use for barracks and training halls.
