sometimes, i will have acquired a fief and don't even know it until i go there and i get money (i don't even recall being awarded it). a page in the report screen would be nice, is there a way to see your holdings?
Well there is your character's entry on the character tab. It shows the fiefs you have, which can be accessed also by another tab, but it only shows the fief's prosperity and garrison number and how long a siege will last.
You can hit 'Q' or click on Quests, click on the Characters tab and it will list your holdings. It also lists renown, what faction you belong to and whether you rule or are a vassal.
