The names humans have for many of the flora and fauna of the Valley come from Rovari, the Daraz language (Daraz are native to the Valley, humans are not). This particular creature is called merev gombi in Rovari, which literally means “hard sphere.” Humans usually just call this animal “merev.”
Merev are the beast of burden of choice for this region. Opportunistic grazers, they’ll eat just about anything placed in front of them, making them extremely easy to maintain. They’re slow but sturdy, and nearly indestructible. When spooked, they don’t run: they pill. If you get into a spot of bother, you know your cart will be more or less where you left it.
The merev’s hide is too tough for many predators to pierce, and its center of gravity too low for them to knock it over. So most predators simply don’t bother with them. YOU might get eaten, but your pack animal won’t.
The merev is not an insect; it is yet another of the many monotreme species in the Valley.
