Bear in mind that this is an adult fantasy world with adult themes: extreme violence and sexual situations are not unusual here. Your character will be attacked or sexually harassed by others eventually, and if you can't deal with that, then Katarsis is not a good place for you to be spending time. If you are offended in general by what is mentioned above or your government prohibits any of it by law, do not play.
The first and most important rule is that you must never communicate any real-world personal information about yourself or anyone else to another player. We do not want to be held liable for the bahavior of lunatics and stalkers. Revealing real-world personal information (real name, phone number, street address, et cetera) is punishable by immediate deletion and banning.
The second rule is that players are expected to stay in character at all times. Do not discuss events or concepts foreign to the world of Katarsis. Similarly, character names and titles which do not make sense within the scope of this fantasy environment are disallowed and will be rejected. This is a place where people come to get away from the everyday world, and they'd rather not be reminded of its existence.
