This “species” was created when a wizard (one Sherizan by name) attempted to create Gargoyle like creatures to be his minion. The Gar-Monkeys were the natural creature that became stepping stone of Sherizan’s GarGronds (Huge Flying Stone Gorillas)
During an “unfortunate event” at his lair, a few breeding pairs of Gar-Monkeys were released. A few centuries later, they have flourished and spread across the Lands. In some areas they have replaced crows and pigons as the nuisance flying creatures.
Gar-Monkey look like small chimpanzees with long (nearly prehensile) tails and two feathery wings. They are nearly as strong and durable as a human male, though they are a little more than 1/3 the size. Gar-Monkeys are as smart as chimps as well, so they will occasionally use things they pick up. They are also “trainable”, so they are used to carry messages and as entertainment.
note: Many people have captured large numbers of Gar-Monkeys to experiment on them, all in an attempt to make GarGronds of their own.
