Very first dragorn I killed (I think it was a peon, may have been a commoner) gave me a -1000 hit on Children of Dranik. He was located right in the first room of the Bloodfields coming in from Dranik's Scar. After that I got normal faction hits.
Does this match up with everyone else's experience?
In addition, I don't think I've killed more than 30-40 dragorns and nothing else to get the hits, but my Mata Muram faction is at could not get any better. I haven't conned anything on that faction yet, but it was by far the fastest to max I've ever seen.
