Dragonmarks

There are twelve dragonmarks and their commensurate houses. The individual marks can be taken as merits and upgraded much as Vampire Disciplines. The canon prerequisites will stand for the most part. Though if you have a concept and purpose that a dragonmark makes better, by all means let me know. Membership and status in a dragonmark house can be reflected with the social merits (i.e. Status, Resources, Allies, Retainer, Mentor, etc).
