From publisher blurb:
The Heshek desert appears to be nothing more than a vast barren waste, seemingly devoid of life and therefore an unlikely region to find strange and fabulous beasts. For the uninitiated this remains true, but in reality the desert abounds with unique and fantastic creatures. If one has the diligence of a true explorer (and, of course, the willingness to risk life and limb,) then the desert is a veritable cornucopia of monstrous delights . . .
Blackdyrge.
The enigmatic sage of monsters returns in Blackdyrge's Bestiary: Perils of the Burning Waste. Here the intrepid chronicler of monstrous lore explores the trackless expanse of the Heshek desert, cataloguing five fearsome creatures for inclusion in his infamous bestiary.
