you name it.

Regular adventures:
Here is a few you could try and contact.
I can’t vouch for them as I haven’t RP’ed much with most of them, nor can I say (at this moment) if they are still active, but in any case here is a quick list gathered from scrolling through the forum.
Bare in mind these are just alliance side.
there are a few neutral pirates and other such groups who does cross faction RP together.
Might I also recommend you install the addon Total RP 3, if you haven’t already,
its a neat little addon that allows you to further detail your character with a last name, backstory and other such neat little things.
