Player Killer

PK
A Player Killer, abbreviated as PK, is a PC who has killed another player in-game.

PKs are identified by their red name, instead of a black one.

If you kill another player in-game, you receive what is known as "PK Status", and a notification is sent to the global board saying who you killed, along with text telling of your status as a PK. Your name will turn red, and you will keep PK Status for as long as you live.

If you die in any way with PK status, you lose the effect, returning your name to black.

PKK
A PKK is someone who kills Player Killers. They are not distinguishable from regular PKs, but most of the players who are PKKs are in guilds dedicated to the cause. Some players are also vigilante PKKs, working alone.
