I don't understand why people think this Jarl thing would be cool, everyone hated being king in Fable 3, in morrowind you could have your own hold but all it meant was a place to sleep and some npcs you could buy and sell stuff from. Also people say a Jarl wouldn't need to be boring, but Jarls are politicians, they are like state senators, their jobs would prevent them from going out on adventures because they would have to stay in the keep to hear people worries and complaints, settle legal disputes etc etc etc. Sure bethesda could just say "naw go out and adventure" but I like to think that they actually care about thier own lore.
