Orion to SE, warrior to NE seems best. Warrior should turn around so that it is on turn 51 in the hills 1SE from flood plains city. From this position it takes 6 turns to get there. I think we can take 3 more moves before heading back.
Edit: actually turn 52 might be enough. Because then the settler and warrior, would be in the hill same time. in this case warrior could do 4 moves before it has to return. However I prefer that warrior has a turn to check the fog before settler gets there and like more 3 turns alternative.
