The Ashes of Prague
One of only two surviving Primogen where once there were 9, Charlie is a young vampire to be a Primogen, though still 300 years old. He is a strong man, though not well versed in politics. He is more inclined to solve his problems with a show of strength than with diplomacy, but the Lancea Sanctum thinks with the right Primogen they might get soften him, allowing for a strong Prince but not a warlike one.
He has said he would happily be Prince, and despite what some think he is not stupid, so this is perhaps not as bad of an idea as it could be.
