All I'm saying for this is that you're going to need a truly experienced guild member to play the Dragonborn, someone who has a long record of sticking with roleplays to the bitter end. With so much of the plot dependent on a single player/character you're going to also have to work with and rely on them to drive a lot of the plot of the roleplay, as well as give them the creative freedom to do the aforementioned. Playing the main character of this is going to be a big task for whoever takes it.

Subbing to see where this goes.
