In the prologue of A Dance with Dragons , Haggon (a skinchanger) forbids three things to a skinchanger:
- To eat of human meat.
- To mate as wolf with wolf.
- To seize the body of another man (this is the worst abomination).
As we saw in A Storm of Swords,
Bran seizes Hodor, but these rules clearly define that this is the worst abomination.
Are these rules just a code of ethics or does Haggon know what he is talking about because he has been a skinchanger for a long time?
