Haven't touched Dragonborn yet with how I play my game (I'm playing as Menora in-game and she hasn't even started the main questline of the game yet, so she's not Dovahkiin yet in-game).
Personally I don't mind for spoilers. I can only speak for myself though.
As for ideas, maybe start with dragons attacking, kinda like the start of Mass Effect 3? That way we can distinguish who is and isn't dragon born?
