When building your character, it is important to note that you are above the average fair. You are paragon! You have done things not even the average hero has done.
This means that you are all special! You are a rare commodity, there are few like you. As such, it is important that your character is well fleshed out and stable! Constantly changing would harm the experience, and will not be allowed except in extreme circumstances (I.E. incurable death). YOU HAVE BEEN WARNED!
Best of all, you are all friends! YAY! In fact you are the best of friends! Why else would you have traveled together for so long? As such, play nice. Arguments will be resolved in a civil manner. If you don’t want to face the player yourself, tell me and I will talk to them about it. We will all be adults, if that is too difficult then this game will probably not be for you.
