You begin returning to the aircar and meet the Notui along the way. They have been waiting for you and watching from a distance. They agree to lead you back to the aircar to avoid difficulty. Whenever asked about the black pyramid, they just dismiss it as some alien magic and talk about the Sathar as the evil worm invaders who inexplicably love violence, a concept they cannot grasp.
It is late afternoon by the time you get to the aircars, get them up and running, and get back to communications.
From the Eleanor Moraes, they appear relieved to talk to you again. They are continuing with the repairs but have received a distress call from those trying to reach the Moraes. Apparently those two survivors you sent in the Explorer could not cross the river and are stuck, needing aircar support to get them across.
You are at the S'krllk/Bartja crash site.
In the south region, you have not yet:
1) Investigated the glint to the south
2) Investigated the shiny object under the river
3) Completed assisting the two survivors of the ship (Bogan Doorem, the Dralasite cook of the Osprey and M'Kix Rix'z, Jr. "Junior," the engineer). They are are currently stuck at hex 1A. (Also, you will recall that the Sathar took the captain and remaining surviving crew hostage to the north--probably to the same place where they took your captain and engineer. The other crew members either died in the crash or were slaughtered by the Sathar.)
As you talk, you think you hear the Moraes state that there were four survivors in the explorer. You ask them to repeat that, and they confirm that there are, in fact, four survivors of the Osprey needing rescue at A1.
