Killed him twice working on pally epic faction.
First time
Heretics -1000
Deepwater Knights +1000
Gate Callers +1000
Craftkeepers +1000
Crimson Hands +1000
The second time I killed everything maxed out in both directions...the following guard kill I got, "..can not possibly get better/worse"
Heretics -909
Deepwater Knights +709
Gate Callers +709
Craftkeepers +709
Crimson Hands +709
I feel like the correct faction is going to be +/- 1000 the previous guy who posted most likely maxed out.
Also his location is in the cleric guild deep in the city aggros by standing against the door
