My idea is this: Make a Dragon Hunter Faction. The Faction revolves around all races that are expert bows men and sorcerers, from destruction to conjuration. The Player can join their ranks, but has to prove its worth by slaying 15 dragons. So there be a slayer system to where it keep track of how many dragons the player has slew.
When joining their ranks, the player has the ability of joining them on hunts, have them as followers, and even rank for every max number of dragons required to rank. I would imagine to spar against the player brothers and sisters. Three out of the pack, will be dragonborn like the player, but known as brothers and sister. The three also has their separate opinion on Sons and Imperial. Two will join separate ranks. The third will be rebellious and figure he himself should be high king.
Lots of detail you see... Just thought to share my idea and see what you guys think
