Nuranar , you bring up good points that probably should be resolved, either in a negative or positive way so that we just don't leave any loose ends hanging. Calnan, Callath, and Adeline can take out everything at Doran's trial where I plan on having him executed by hanging. They can testify against him and be present at his execution. That would be the most realistic end, IMHO.
As for Acacia, I don't think that it would be likely that she would be executed. She wasn't seen by any Gondorians while in Umbar. The only person to really have anything against her would be Adeline. Acacia was mostly working behind the scenes. But we'll let Acacia decide her fate!
Jurex is dead and so is Devon. I think Ambassador Thrann should only be mentioned in like a post about Devon's funeral, which Calnan, Callath, and Adeline would probably have for him. I think, realisticly, that Ambassador Thrann would have been removed for being so blind and naive with Doran and letting him take so much control.
Secondary characters-everyone just tie up whoever they control. I don't know all the personal stories for each one because of the length of this game. Sound good, Nuranar?
Thanks, Nuranar, and right back at ya!
