Earcerci are bipedal aliens which are descended from deep soil burrowing insects. They have short limbs, a flexible exoskeleton which covers their body in rib-like structures, and walk with a bow-legged gait. Their brains are highly developed, and possess a unique five-lobed structure. Unlike most insectoid sentients, the Earcerci are individuals, and do not share a hive-mind. Earcerci society however still maintains many cultural holdovers from a hive-mentality, including a rigid caste system.
