Ewoks were curious individuals that stood about one meter tall; they were omnivorous and used spears, slings, and knives as weapons; they also used hang gliders, battle wagons, and bordoks as vehicles. Although extremely skilled in forest survival and the construction of primitive technology like gliders and catapults, the Ewoks had yet to progress past stone-level technology when discovered by the Empire. They were quick learners, however, when exposed to advanced technology with simple mechanical processes and concepts.
The Ewoks were in allaince for the Rebellion towards the Empire. So yes they are good guys. The Ewoks are also a tribal society meaning they have a chief. Think of a Native American tribe with the different men in that society.
I am just wondering what your thoughts are toward the Ewoks?
