I just beat the campaign, but I think I missed some of the dreams because I only took 11 cycles (plus 5 from a passage), so I was very confused about the lore. From what I picked up, the drone master was sent out to find something with a handful of requirements, and the chieftain scav meets these requirements.
What are the requirements?
Why is the data needed?
Who's the iterator?
Is the dronemaster partially robotic?
The iterator says that the outside world is dangerous, is it more dangerous than usual, or just average rain world?
