Katariki stirs, but doesn't open his eyes. He's still stunned from the thump you gave him back on Earth.
You sit up. You can see the other end of the Surgeons' portal. A hundred yards or so from you is a chasm, what looks like a natural cleft in the ground. You almost didn't see it, so densely packed are the Surgeons over there. But above that chasm is a great portal, the parallel to the portal hanging above MetaHuman Tower back on Earth—bizarrely, though, this end of the portal is pitch black, and expels a curious black darkness.
The Surgeons have some sort of equipment over there. You can't make out the details, but that's where you'll find the Surgeons' spatial conduit device.
Then a whispering ripple passes through the Surgeons all around you, and the few thousand nearest to you turn your way. You have been noticed.
Another moan from Katariki. It'd be fairly easy to knock him out completely if you wanted to hand him over—and win the Surgeons' favor.
