Chasmfiends are large, monstrous creatures found in the world of Roshar, a setting in the Stormlight Archive series by Brandon Sanderson. They are known for their massive size, often reaching several stories tall, and their tough, armored bodies. Chasmfiends primarily inhabit the chasms and deep ravines of the landscape, where they hunt for food, including the smaller creatures that also dwell in these areas. These creatures are characterized by their multiple legs and long, segmented bodies, which allow them to navigate the rocky terrain. Chasmfiends are also notable for their bioluminescent features, which can glow in various colors. They play a significant role in the ecosystem of Roshar and are often seen as both a threat and a source of fascination for the inhabitants of the world.
