Two challenges, for those who like challenges.

Theoretically it is possible to make the three nations vassals again without building forts in their territory. Hints abound that a portion of the populations in said nations would not enjoy Havenite military presence, and the main character has the option to reflect about that in dialogues.

No forts, beyond the initial one in Haven territory, might be really harsh. One fort per nation might be quite difficult, too, compared to building six forts.

Right now, trying to pull just one fort per nation, since a true multicultural party makes for an interesting game. But for a second run, it might be interesting. What do you think?
