Xenotermination Ltd.
This small group of highly capable combat specialists and spellcasters makes a living by hiring themselves out to capture or kill formidable Wildspace creatures. Typically, they are hired by an individual or a business whose welfare (financial or otherwise) is threatened by a monster that has defied less potent attempts to remove or subdue it.
From time to time, Xenotermination takes on temporary members, who are sought out because they have a particular talent. Anyone who wants to offer their services, on either a permanent or occasional basis, is welcome to visit the building where the present members of the group house themselves.
