Player character
A "player character", often abbreviated as a "PC", is the representation of somebody's in character persona. They can develop mentally and physically and can create relationships, enemies, friends and influence the IC world. As CLOK is about roleplaying, many often draw a line between their out of character selves and their characters. To put this plainly, your character is not you. They can be a fictional version of you, but ultimately your goals and relationships as a player should be separate and not influence your character's actions directly. It's fine to seek roleplay among people who are friends out-of-game, but entirely not fine to allow your like or dislike for another player to influence your character's actions without any sort of reason in-game, especially if it brings harm to another's enjoyment of the game. Bringing drama from out of the game into the game is taboo and can be considered a type of harassment.
Remember, we're all here to have fun and be immersed in a fictional world. You may not be your character, but you can choose to keep things fun for other players. There's an rp guide available if you're new to the concept. Also remember to read the policy.
