The first Dragon Age II DLC has been announced. It is a party character in the same vein as The Stone Prisoner was for Dragon Age: Origins. For those who preorder Dragon Age II you get this extra content free. The preorder must be in by January 11th to get the free upgrade to the Signature Edition. If you miss it you can still buy it as per normal for 560 Microsoft Points.
The DLC called The Exiled Prince adds Sebastian Vael, the last surviving heir of his family who were brutally murdered. You can choose whether to help him reclaim his title or press him into service towards more pressing matters. He is a noble archer and brings his skilled bow work to the party.
Unknown at this time if this exclusive to the Xbox 360 as PS3 and PC are absent in the mention of price.
