My main LS is Lacasteoubliee ( "La Caste Oubliée" means "The Forgotten Caste" in French )
As the name implies, it is a French-speaking LS. We are almost only Quebecers but do have a few people from France and Belgium as well. It is a general purpose LS, with people from levels 1 to 75. No, really. It's just that most the of the 60+ usually have another LS to be able to do things the few scattered High Levels in Lacasteoubliee can't help get done. And a few of the 70+ barely make any appearances, such as Loualie (BLM), Balzac (BLM), Weedeater (SMN) and Potcaster (BLM). The most noticeable members are the shellholder Mihmendra (BLM), Jago (SAM), Laurewen (WHM), Rockfist (BST) and me of course (PLD) lol.
I'm also with NorthernExposure, commonly referred to as NE.
I got invited there by Derufin, upon Sarevok's request, or so I've heard, since I'm an old acquaintance of Typo. I'm not really involved in it because I haven't beent here for long and they don't much in terms of LS events, but I know there are quite a few high level players there, but when they're on NE, it's mostly about the fun, or leveling other jobs than their main. The High Levels only get together to help themselves with things such as missions and quests. Not much high level content involved, as NE seems to consist of people like me that aren't too fond of the overly competitve and jealous world of HNM hunting.
And then there's Dynamislordhnmls :p
It's a Dynamis LS, leaded by Lydia. They do Dynamis once a week. Not much else to say. I go in the run, respect the rules and people, and do the mission, while HOPING to maybe get a piece of AF. It's as simple as that.
