It's about time, too.
I hate overtext but love irony.
There is a separate quest which has an action that can result in placing a star in a certain type of location. I believe this is the only way to place a star token during the Far Harbour campaign.
Both card 30 (staged at the start of the scenario) and card 31 (added at the start of the scenario) have ways to add a star and are never trashed. So there are always at least two ways of adding stars.
