The Stingwings hail from the storm-wracked, high-pressure world of Vespid where they evolved amidst drifting, lighter-than-air rock islands. Each island is an independent nation with its own leadership and traits. Upon first contact with the Tau, the Stingwings displayed no hesitation in joining the Tau Empire and now fight in Tau armies where they are afforded an uncommon respect by the warriors of the Fire Caste.
