I am not sure if what you are looking for exists. I know that I have started this concept of a guild that I am building slowly. Is it based on another universe? Well, maybe mildly, in that it has some similarities to the Witcher. But I am working on making it a WOW story, with lore compliant storylines and rpers who care about a story driven campaign.
You may contact me in game by mail or here on the forums. If you wish to investigate the server, I know that Moon Guard has a reputation that is hard to deny. However, I also know it has a lot of rp, and some very fine rpers. They are not easy to find.
