The Schostri represented a species of insects akin to wasps, equipped with stinging capabilities. In battle, the Vagaari race employed schostri, keeping them in gauntlets with openings hidden beneath their clothing. Upon sensing adrenaline from their Vagaari companion, the insects would amass into stinging clouds, capable of inflicting a multitude of stings on adversaries and killing nearly all humanoid life forms, while simultaneously protecting the Vagaari. Furthermore, the elite members of the Vagaari Empire harnessed the insects' costly toxin to devise a lethal airborne poison, able to eradicate all individuals, including the user, within a twenty–meter area.
