They can't have you have the same face as some random NPC can they now
Makes you wonder what poor fellow they used to scan for Dragonmens though

There, when you picked up head that was set for an NPC, that NPC get another head from your character selections ... right now we have 6 heads per race reserved for PC ... it seem like enough to make sure that no NPC will be players twin sibling. :P
