A Union of Role Players that a few years ago  saw the need  on SecondLife to expand the roleplay experience.  It is not a RP Group but consist of many RP Groups.

It is the Trilogy of many Sci Fi Role Play Organizations, that together that shares Storyline and events. 

How it works:

Each month we share different group location to host the meeting.
We start with a basic talk and sharing ideas to help each other. About a  story line and  let each Organization in their own way adds their own Chapter to the Storyline based on what happened before them. Then shares it back so others can add on the story
