What is chasm fiend?

Chasmfiends are large, crab-like creatures found in the Stormlight Archive series by Brandon Sanderson. They are native to the world of Roshar and are commonly found in the chasms that run through the Shattered Plains.

Chasmfiends are considered apex predators and are one of the most dangerous creatures in Roshar. They have a hard exoskeleton that is nearly impenetrable and powerful mandibles that can tear through anything. They are also incredibly quick and agile, able to move in any direction with ease.

Their most notable feature is their ability to use Stormlight, a magical energy source found in the world of Roshar. Chasmfiends are able to absorb Stormlight through gemstones embedded in their carapace, which they use to power their attacks and abilities. They are also able to release this energy in a powerful blast, which can be devastating to anything caught in its path.

Chasmfiends are highly valued for their gemstones, which are used in many different forms of magic on Roshar. Hunters often risk their lives to hunt these creatures and take their valuable gems. However, chasmfiends are fiercely territorial and will often attack any creature that enters their territory, making hunting them a risky proposition.
