Well, Hammi's cities are pretty close. The re-base icon turns green (relative to marble) at 8w3s, 8w3n, 11w.For starters, I'm fine with Erkon's prohibition on fishy fog-gazing, but using the airship's rebase function to decide where we want to rebase it is simply part of the airship's capabilities. We have OBs with Hammi and Joao enabling us rebase to any of their cities. Hammi has 3 cities to our west. We can rebase to them without prior knowledge of where they are (that is, now, if we want). If we're going to scout west, we might as well rebase there first. Before that, I think we should scout the east island and the barb island, because that will tell us about our immediate REX plans.
Maybe we want to make plans for acquiring a couple .
But re-basing doesn't give us knowledge of the land in between for settling.
Knowing the east island would be fine, but I think we will settle there no matter what . Knowing the barb island is fine to satisfy curiosity. And there is the chance that the 6 visibility we get there gets us knowledge about more land in the east.
