Your faction standing with Corrupt Qeynos Guards got worse. Your faction standing with Guards of Qeynos got better. Your faction standing with Kane Bayle got worse. Your faction standing with Circle Of Unseen Hands got worse. Your faction standing with Bloodsabers got worse.
After killing Hadden for the earring, always kill these 2 if you're born on Qeynos grounds.
This has happened to me twice so far: I'm kiting the (Corrupt) Guard Sironan with my druid out in the area between the Sayers' hut and Blackburrow, and just as I've nearly got him finished off another guard (a good guy) comes strolling by. As soon as the good guard realizes what's going on, he comes chasing after me and I have to run to the Blackburrow zone to escape. Freakin' hassle, but I guess guards have to stick together nonetheless!
