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.

Jill, Eustace, Puddlegum and Prince Rilian are attempting to escape from Underland when they encounter a gnome who tells them about the land of Bism. Rilian wants to visit the land of Bism- his father Caspian explored lands to the end of the world and he thought it would be fitting if he explored lands to the bottom of it.


 * 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. There were blues, reds, greens, and whites all jumbled together: a very good stained-glass window with the tropical sun staring straight through it at mid-day might have something the same effect. - From The Silver Chair, Chapter Fourteen: The Bottom of the World
