A few questions about elderlings, dragons, magic etc. [general spoilers]

6. now that I think about it I dont think its becuase they were abandoned. I am rereading dragon haven and I read that changes often occured to those who tended the cocoons. There is never any mention of them being given blood or scales.

7. I wonder what would happen if the duke of chalced got hold of dragons blood. I'm guessing that the dragon would get so pissed off tat mutations along the lines of greft would occur. Probably the dragon would increase the speed enough that it would hurt a lot. Even if the dragon did nothing the chances are the duke would still die. Quite ironic to think that he would live for centuries with a willing one.
