The Duststalker is a lean desert predator of Inland Thazvaar's Infinitude Deserts, spanning 8 to 12 meters and weighing 800 kg to 1.2 tonnes in the wild. Camouflaged as large rocks in desert-mountain transitions, it ambushes wanderers and herds with explosive speed, fangs and claws claiming prey in a blur of concealed fury. There is no safe way to bypass one. Simply walk past and hope it does not notice you. Its underbelly fur is popular among Thazvaari due to being thin enough to wear during the day but thick enough to keep warm at night.
A tiny city variant less than 0.2 meters in length exists in major population centers across the planet, having adapted to urban environments over generations of human spread. The city variant retains the predatory instincts of its desert ancestor compressed into a frame small enough to inhabit walls, drainage systems, and the gaps between structures, hunting vermin and small fauna that populate the spaces humans create but do not maintain.
