Dragon Age: Origins gameplay and discussion thread.

I think that none of the regular rules apply to the player character, since he/she is a Grey Warden. I think there's something Riordan says about everyone from a thief to a king being allowed to be a Grey Warden, during the landsmeet bit.

Yet there are still a lot of actions that the PC can take to alienate the NPCs and even make them try to kill the PC. It's just seems odd that no one even thinks it's worth a raised eyebrow and a -1 to your influence for having the PC be a blood mage. Putting it into context, during the Landsmeet, Loghain had countered my arguments against him with "This Grey Warden is a Blood Mage!" it would have made a lot of sense if that swayed some of the nobles to his side. Given that Blood Mages were the original cause of the blights in the first place, I can't see the nobility reacting well to it in a power struggle.

I can understand no negative consequences for the Ravager (or whatever the 'evil' warrior specialization is called), since it's never really discussed much in the game. However, Bioware put a TON of content into the game about Blood Mages, and almost all of it is about just how extremely bad it is and how Blood Mages are considered outright evil by most of the kingdom.
