While the flight plan shows the route they're taking, it's effectively useless for anyone who can't fly, as all f the portals they're traveling through are indicated to be at heights of a couple hundred meters off the ground. An effective security measure, to say the least, given that it prevents most kinds of forces from moving through them, yet still allows one the ability to cross dozens of worlds rapidly, without using plane-hopping abilities.<br/><br/>The most likely scenario for how someone knew Reaper, and what it was planning, was that it had been observed by a drone, and the report had made its way to someone<em>very</em>high in Barid's hierarchy, likely one who knew of, if not Reaper specifically, then could identify it as something more than a mere footsoldier. Which also put pretty good odds down that they knew Draiss had returned... which meant that time might be short for Reaper to make contact, and get back.
