i also kinda wonder if any of the kobolds born of our dragon will be better in any way than those of the previous dragon. i think it's doubtful and their appearance would be the only difference.. but i still wonder.
would be interesting if electing one of your direct off spring to lead the kobold horde gives them a moral boot in act 4. or suffer moral loss in act 4 but double moral boot in act 5? or maybe a boost other than moral? like access to a hidden plot line? hmm...
