Someone has already claimed the Jarldom of the Pale, and unless I am mistaken the sign-ups for contesting Jarl/Duke titles is over, however you can play within it. So you won't be Jarl, but Count (or whatever the local variant is).
Well I created the back story of the Pale as well and it's entire culture.It's a 850 year in the past prequel so its not your jarldom, or you could still join and show the rise of your Agorath 1 character's family >.>
