The drunk
A genius nord warrior that quickly climbed the imperial ladder, but once he was high in command refused to participate in the stormcloak imperial feud. Was thrown out of Skyrim, became a drunk, and by accident returns to Skyrim after sleeping the night in a carriage. He still get's psycho notions and unloads on people who he thinks are scum. Becoming a dragonborn gives him a new purpose and a way to clean up his act.
The scientist
An[undecided race] who lives for science. He's cunning and manipulative, but does not consider himself evil. He still hasn't decided if innocent killing is forbidden in his rulebook. So he could go either way as a character. Being a dragonborn interests him and he wants to see how things will unfold.
