Kitins are huge and gregarious insects whose collective memory places homins as natural enemies and predators to be exterminated. The Fyros miners crossed paths in 2481 while exploring underground galleries. This meeting marked the beginning of the Great Swarming. Kitin workers collect resources for the nest while Kitin soldiers protect and expand their territory and attack intruders. Kitins are ferocious and merciless creatures with a superior intelligence compared to other animals of Atys.
