Physical Description
The thornback is a massive, tortoise-like quadruped with a thick shell covered in rows of plate-like scutes. Spines and bony ridges protect its shoulders and flanks. Its hide is sand-colored and heavily wrinkled, with thick-lidded black eyes that appear half-asleep even when alert. The deep rumble of its breathing is often mistaken for distant thunder.
Wild Behavior
Thornbacks travel in slow-moving herds across ancient desert routes, following unknown migratory patterns that ignore geography, political borders, or weather. They graze on mineral-rich lichen and sun-bleached scrub, occasionally burrowing into soft rock to rest. If one is separated from the herd, it enters a heightened stress state and may become aggressive toward nearby creatures.
Domesticated Behavior & Uses
Despite their size, thornbacks are gentle when raised in caravan culture. They can haul multi-ton wagons, moving slowly but tirelessly for days without pause. Their shells are sometimes inscribed with dye-marked trade glyphs or prayer symbols. Visari and desert clans view them as sacred; some nomads believe their movement keeps the desert in balance. Imperial handlers use sedative sandroot and melodic chant to bond new haulers to the lead walker.
