A Dimetrodon sinks into torpor under the desert sun after polishing off the remains of a hapless human hunter. Despite their reptilian appearance, Dimetrodon and its kin were more closely related to mammals like us than to proper reptiles like dinosaurs. Nonetheless most paleontologists assume they possessed a “cold-blooded” reptilian metabolism sensitive to environmental temperature changes.
So far all of Dimetrodon’s remains have been uncovered in the southwestern United States or Europe, but I chose to base this fantasy desert backdrop more on the Australian Outback. Most fantasy deserts seem to draw from the Middle East, North Africa, or the American Southwest, so I felt an Australian inspiration would be a welcome variation from that pattern. Besides, Australia is well-known for housing a number of dangerous reptiles.
