We sail toward the mainland, and see two shapes approach in the sky: flying men! They're carrying spears! One of them stabs our lookout!
But the lookout isn't badly injured, maybe it was just a warning? After all, we are the invaders here. Their flying suits suggest they have advanced technology. And we don't know the size of heir armies.
Should we try to capture the flying man? Would that provoke more aggression? But it might be our one chance to get useful information before we reach land, while we still have a chance to turn back. Or should we proceed with extreme caution until we know more? Or do something else?
