Chulls

Chulls are large domesticated crustaceans used as heavy draft animals across Roshar. Their physical scale, armor-like shells, and powerful claws make them intimidating, yet their ordinary function is practical and agricultural: they pull wagons, carry burdens, and perform labor under human direction. In the evidence surrounding Kaladin’s enslavement and an Alethi chasmfiend hunt, chulls appear not as monsters but as resilient working animals whose bodies have been incorporated into systems of transport, commerce, and warfare.

Appearance and Physical Capabilities

Chulls are nearly as large as wagons, with box-shaped bodies, bulging stony shells, thick trunklike red legs, and red carapaces. Their antennae move continually when they are alert or unsettled, while their claws are strong enough to snap a man’s arm. The combination of armored bulk and crushing appendages gives them the appearance of dangerous beasts, even though their size is also what makes them valuable to human communities.

Their armor is not merely decorative. The hard shell protects the animal while it works across rough terrain, and the heavy legs provide the power needed to move large wagons. The narrative consequently presents the chull through both threat and utility: its body suggests violence, but its domesticated behavior makes that violence exceptional rather than routine.

Behavior and Domestication

Despite their formidable claws, chulls are described as docile, particularly when domesticated. Soldiers in the Alethi army have apparently received little more than a halfhearted pinch from them, a detail that sharply undercuts the initial impression created by their anatomy. The chull’s danger remains real, but daily interaction with humans is governed by habituation and control rather than constant aggression.

At night, the chulls in Tvlakv’s caravan settle down and withdraw into their shells, taking in clawfuls of grain as they rest. Once retracted, they resemble three lumps in the darkness, scarcely distinguishable from boulders. This behavior gives them a moment of independent animal presence: they feed, shelter themselves, and become part of the nocturnal landscape even while serving the caravan’s economic purpose.

Labor in the Slave Caravan

In the slave caravan carrying Kaladin, chulls are the engines of movement. Their bodies pull the wagons through the open landscape, allowing the slavemaster and his mercenaries to transport chained human cargo over long distances. When the caravan halts two hours after First Moon, the serving boy Taran tends the chulls while the mercenaries build a small fire. The animals are fed and allowed to settle before Tvlakv checks the enslaved people one by one and distributes water.

This juxtaposition exposes the caravan’s hierarchy of value. Tvlakv treats the slaves as investments whose health must be monitored, while the chulls are maintained as the means by which those investments can continue moving. Both people and animals are incorporated into the caravan’s economy, but the chulls possess the practical power on which the entire journey depends. Their care is therefore not compassion in any simple sense; it is maintenance of essential laboring bodies.

The chulls also give the caravan a distinctive rhythm. Their fidgeting antennae mark the lead wagon’s eventual stop, and their massive forms explain how the vehicles can continue rolling well past noon. Human movement in this section is organized around animal endurance: the wagons stop when the draft animals stop, and the caravan’s progress is measured through their capacity to keep pulling.

Use in the Chasmfiend Hunt

Chulls also serve in a very different Alethi setting: the organized hunt for a chasmfiend. On the hunting plateau, away from the attendants and the bulk of the soldiers, hunters lead a lumbering chull around the perimeter while it tows a rope over the side of the cliff. The rope drags bait intended to draw the chasmfiend from its nearby nest.

Here the chull is not simply transporting a wagon. It becomes part of a carefully arranged hunting mechanism, linking the human hunters, the cliff, the bait, and the anticipated movement of the greatshell. Hog carcasses and hog’s blood are used to attract the chasmfiend, while the chull supplies the steady pulling force needed to position or drag that bait. Its docility makes such coordination possible: the animal can be guided into a dangerous environment and made to participate in a military spectacle without being treated as an independent combatant.

The hunt reveals a contrast between scales of creaturely power. The chull is huge by human standards and equipped with a shell and claws capable of serious injury, yet the hunters use it as a controlled implement in preparation for confronting an even larger beast. The animal’s strength is respected enough to be useful, but not enough to grant it authority over the operation.

Narrative and Thematic Significance

Across these scenes, chulls occupy an intermediate position between animal life and equipment. They are living creatures with recognizable habits—feeding, retreating into their shells, and reacting through their antennae—yet human institutions primarily perceive them through function. The slave caravan values them as draft power; the hunting party values one as a means of transporting bait. Their bodies are therefore both biologically specific and economically instrumentalized.

Their recurring presence also broadens the material world beyond human conflict. The chulls’ shells, claws, grain, and labor make transport and hunting feel dependent on nonhuman capacities rather than on abstract logistics. At the same time, the scenes do not grant the animals speech or human-like intention. Their narrative agency is limited but not absent: their endurance, docility, feeding, and movement determine what human plans can accomplish. Chulls thus embody a central tension in the setting between domestication and power—the powerful creature made useful by discipline, and the useful creature whose own physical nature can never be completely reduced to a tool.
