Just because a cavern or dungeon is deep does not mean that it is part of the Darklands. Most such places are simply natural or artificial caves that connect only to the surface and do not delve any deeper. In order to truly qualify, an underground location must possess connections to the greater system of tunnels and caverns of Nar-Voth or Sekamina. Although there are many entrances to the caverns of the Darklands, a few stand out either in size, notoriety, or both.
