The so-called "Cold Trade," as it is known in the Calixis Sector, is the illegal trade of xenos commodities by unscrupulous individuals who deal with the alien either for profit or for survival's sake. Though highly frowned upon by the Inquisition's Ordo Xenos, many of these items are not considered outright illegal due to the impossibility of categorising and banning every item, device, or object that may or may not have been made by nonhuman hands. The legality of such items are further muddied by the fact that certain individuals and agencies have had their right to exploit xenos races, conduct commerce outside Imperial space, or profit from alien plunder enshrined in law since the Imperium's founding. Foremost amongst these are those individuals or dynasties who hold a Warrant of Trade
