Salamander

Salamanders of the Narnian world were dragon-like reptilian sentient beings that lived only in the lava rivers of Bism. They lived far beneath the Narnian earth and were too white-hot to look at, and they shared their habitat with flowering gems and the Earthmen.

Salamanders were wonderfully clever with their tongues since they possessed the ability of speech and were very witty and eloquent.

During the last days of Narnia, salamanders also assisted the dragons in destroying the world.

Trivia

 * "Salamander" is Greek for "fire lizard", and these creatures are associated with fire in several legends.
 * In real life, salamanders are a type of amphibian, not a reptile.
