Resolution for mutton island? Mods?

Is there any way to expel the conquerors from mutton island? Or do you have to side with the conqurors to visit it ever again? Or, as the wiki claims, is it permanently locked as blockaded? If so, do you know of any modders who have made a resolution, or preferably multiple possible resolutions, for mutton island?

modding sure looks intimidating. maybe ill gather up some bravery someday and take a crack at it myself

There are several possible endings. Once you visit enough for one to trigger, that ending will remain in effect for the rest of that captain.
