The Schostri were a species of insects similar to wasps that were armed with stings. The Vagaari species utilized the schostri in combat situations, storing them within holed gauntlets under their clothing. Once the insects perceived the adrenaline of their Vagaari host, they formed swarms, capable of stinging their enemies a dozen times and killing almost every humanoid, and encircled the Vagaari. The Vagaari Empire's high–ranking members also used the insects' expensive to manufacture toxin to create an airborne poison that could eliminate everyone, even its user, within a twenty–meter radius.
