Even better.

You know, thinking about the warfare side of the game, it is indeed very difficult to get through large sea/ocean into another continent, far far more so bringing in an army.
Specially if the continent's fiefdoms had some sort of alliance. Let alone talking about logistics like food, water, shelter, etc.
[thinking smuggling in food prior, or just creating stockpiles of food inside area before even attacking, choosing best beachhead, etc.]
Attacking a single area/'fiefdom' would alert the other fiefdoms and get them to mobilize a defense and/or attack force.
Even if you can sneak the MC into the area, can't do much by himself, he may be able to get a leader of a fiefdom to join his cause before MC commits an attack fleet. [perhaps a fiefdom that has been overly taxed and/or opressed by a larger fiefdom].
Been a long while since I played, so I don't remember if MC described a rough plan or two. Can't really sneak into the area?
[plus if anything goes wrong, MC would be all alone without an army... lets face it, he will bang a few people and get help
