I simply have to ask: Level cap at 12 and ruler of the forgotten realms, how do these 2 match? Something smells odd.
Power doesn't simply come from class or character levels. Joffrey Baratheon was a level 3 dipshit. He was also the First of his Name, King of the Andals and the Rorynar and the First Men and Protector of the Realm. Palpatine was a level 30 Lord of the Sith or somesuch, yes - but he gained power through scheming and politics.
