Concepts to create
The Hero - A Proto Human of the Civilian Class, a Miner, one who kind of fell for his own sense of importance with the prophecy, and believes the Journey West is part of that plan.
Ally - A Fae Dragon from the West who has integrated himself as a servant human among other dragonshifter kind. He is a spy, attempting to make his own kingdom among the tribes to the west, and is determined to see if the shifters are a threat. He might be a villain as well. Secondary Role is Jester/Ace/Wildcard.
Villain - A Drake or 'lesser' dragon that is attempting to overthrow the royalty by any means necessary, including helping the humans. His goals are self serving to start.
The Hero - Hybrid Human. An embarrassment, and only kept around as an oddity. His mother claims him as an Omega created human in order to fit in. He serves his mother, but he's in a spot between worlds, torn from his draconic birthright and the absolute evil the shifter society represents.
Which do you think would function best for the story?
