The mature section is a place where anyone can do anythintg they want, the only rule being that unless you are working with someone on a story, and not a roleplay, you may not take control of the other party's character. This section could contain things that may be offensive to some members, and thus this warning is in effect. If you don't like extreme violence, bad language or sex, this isn't the place for you.
