Was playing a Bulwark (Rock A) that starts with 3 Rock crew. A few jumps into the first sector I run into a slaver. He surrenders with freeing.. a Rock crewman. OK, well I guess 4 is better than 3? Then I jump into a nebula and scan around, and I find? A rock crewman! OK, I guess 5 is better than 4? So we make a few more jumps (still in sector 1) and we run into another slaver. I bet you can guess where this is going? Yes, in fact, it was Rock crewman #6!
Sector 2 threw me for a loop as a Rebel (human) defected to my crew and sullied my pristine Rockitude. A slaver in the third sector coughed up the 7th Rock (8th crew) and we rode that out until we ran into a slaver in the 6th sector! We boarded and liberated the slaves (well we liberated the crew, just in a more permanent way) and we were offered help from either a Mantis, a Rock or an Engi. Clearly that was an easy call, we air locked the stupid rebel Rebel and went for the perfect 8.
