He struggled to find words, then caught himself, "Stop," He said, his usual authority muted in the face of the Emporer's chosen, "this area is under quarantine. It is suspected that xeno creatures in the area." He swallowed the knot in his throat, realizing he had just attempted to give an order to a space marine, "I am sorry, I wasn't informed of your arrival. My men have been searching the area. There were reports that an Eldar shuttle had landed nearby while we were in the field, and with them, Tyranids." He gritted his teeth, "We also have support incoming from Commisar Theris, bringing the majority of the company to us."
