Pseudo-Wyvern Drakes are a desert-dwelling species with an unusual bipedal body structure as adults. They start out as quadrupedal hatchlings and slowly start walking on their hind legs as they age. As their name suggests, these drakes are often mistaken for wyverns from afar as they ride the desert currents searching for food. A social drake, Pseudo-Wyverns travel in small packs, working, hunting, and raising young together.

Though it may appear at first that dragons and drakes have much in common, the two are completely separate species. Drakes are smaller and less intelligent than their cousin species, though both dragons and drakes sit comfortably near the top of the food chain. They are always found bearing antlers and leathery wings. Drakes share many of the same habitats that dragons do, and typically hunt in packs.

Iset is taller and heavier than the average pseudo-wyvern drake, but he's a big sweetie. He was born a wild drake and flew into town looking for friends all by himself. He's now a pet or mascot of sorts of Hedges Diner, where he likes to visit large groups of guests, poke around the counter, eat bugs, and lie on a heap of sand in the corner, and he rarely bites. His curious, mild nature is a headscratcher to the townsfolk, many of whom initially believed that Iset might have the drake version of the water-hating, mouth-foam disease that seemingly makes an animal tame, but he's shown that he's clearly healthy. A small number of people believe he's actually enchanted to believe he's a dog, or he's a spirit in disguise, or he's being body-surfed. Even the magic users saying there's no hint of magic on Iset and bringing a nullifier to demonstrate are not enough to change their minds.
