Bism

Bism is the nation of the gnomes, far under Underland and the surface, it is a nation where crystals and diamonds and gold live and grow as food and great rivers of lava flow, it was nearly visited by Rilian.


 * When they got used to it they thought they could make out a river of fire, and, on the banks of that river, what seemed to be fields and groves of an unbearable, hot brilliance&mdash;though they were dim compared witht he river.
