Underlands

The Underlands were the nation/state six thousand feet beneath Underland at the bottom of the isle of Enniare. It was the home of all Gnomes living in Gaen
 where crystals, diamonds, and gold grew and thrived in a similar way to
 plants and whose juices could be harvested for food and drink. Once 
the gemstones died, they fossilised and became the hard gemstones that 
humans are used to collecting nearer the surface of Gaen. The Underlands were also
 full of great lava rivers that were inhabited by Rodelars and Dragons.
