The Curtus are the innovators of the Permia world. They are small and not exceptionally strong, but they have the ability to intuitively solve complex problems. With the combination of elaborate traps, powerful crossbows and crude explosives, they are able to overcome monsters and enemy raiders.
Although they can create complicated devices, the Curtus are not an industrial people. They are perfectly content with a leisurely life free of toil and worry. They have very simple needs and do not believe in property. This can often lead to conflicts with other peoples. A Cibus farmer will be quite upset when a group of Curtus wander into their orchard or vegetable garden and the Curtus will be equally upset when they get attacked for eating fruit hanging off a tree.
