Half insect and half machine, the Insettroidi are a race of creatures that try to conquer the Twilight World. The memory of why they exist, whether someone created them or evolved spontaneously, has been lost for a long time. They are at war with the humans of the Dusk City for millennia, without anyone being able to prevail on the other. They are heteromorphic bugs armed with many kinds of technological implants, like continuous tracks, energy cannons and more. They are all tied to a mother brain in their capital that serves as a hive-mind.
