I just came back last month after six years
Met a whole bunch of people that helped be get used to all the changes.
-Luna is the new West Brit.
-Magincia is a smoking hole in the ground, crawling with ghosts. (and you can't escape via the moongate).
GRI\SnR Alliance - large group of tram guilds that run spawns and help out new players. We usually hang around in New Haven. Mostly OOC.
UP - United Pirates - A pirate RP guild. If you have any interest in RPing a pirate, join up with this crew
Arr! Referred to as 'bloody pirates' by the PGoH. Led by their captain Hawkeye Pike.
PGoH - Purple Guardians of Honor - Another RP guild. They live outside of Trinsic, in their player town, Olympus. Lord British gave them some sort of control over the city of Trinsic before he disappeared. Reffered to as 'dem landlubbers' by the UP. I'm not a member, but have met a few of them through my UP character. They're a good bunch as well.
Mentioning Fel guilds will just start a rant, so I won't.
