It took no less than half an hour for the rumors about the Black Armored Knight PKing someone to reach the ears of the higher-ups in the Devastator guild. At first it was disregarded as someone causing trouble and who would soon be punished by the NPC forces that protect the cities of Conquest.
These NPCs preserved order so that there would be no mayhem inside cities. But seeing that these enforcers didn't move when the Black Armored Knight started PKing, the players thought it was a bug or glitch in the system. However, when the second killing occurred, many players feared for their levels and lives.
The Devastator HQ received several notices about the Black Armored Knight, and how he was strong enough to take on entire parties of level 300 and could easily escape the hunt of level 400 parties. The killings started in broad daylight and ended after a few hours in the afternoon.
