Arion runs the Bree-land Watch, and there's no kinship, but there is a "uniform" to wear while on duty.
Several kinships, including one I'm in, are heavy RP and travel. However, we mainly use /emote, as /say tends to be buggy out there on the landscape. It's actually not clear at all what kind of RP you want, from your post, though, aside from The Watch of Bree. You also just missed an RP plot up in Trestlebridge. I think a couple of folks are running a plague plot, and something's going on in Saldell. Good luck finding what you crave.
Favorite Dev Quote from 2009: Graal: The lack of an instant threat catch up skill is one of the differences in tanking between Wardens and Guardians, just like Wardens dont have a easily used forced taunt. It is unlikely, but not impossible that this will change. Bottom line...Dont die.
