Well no royal blood would be aloud to hang out with commoners, so Cadmar would have to reach the spot of blue blood. He could do that if his dept was paid or by becoming a war hero and, because they are in the process of changing rulers where they don't quite have a king or queen yet, it would be an ideal time for an attack.
For those who don't know Cadmar has two meanings, which is why I use it, the first one being 'From the East' which was my intentional purpose for the name figuring he could be from the east but as a backup in case something happened, which is inevitable in a role play with kings, queens and men with swords, it could also mean brave warrior/fighter. So we could do a small invasion where all the peasants would be given a sword to defend the castle with the guards being caught completely off guard, only few survived and one is Cadmar who killed dozens of enemy's or save the princess or something that would make him a war hero >=]
