Frozen Poets of Velious was the RP guild. They went fishing, did signature / game art, and posted a lot on message boards, along with other stuff I am not sure about.
Not exactly true. The Poets are a RP preferred guild. If you do not roleplay, you can still enjoy the company of the other players. We did do a few photo (screenshot) contests and we organized some fishing trips, but for the most part, FPoV was more a band of gypsies roaming the lands than a dedicated RP guild.
Companions of Norrath was the roleplaying guild. They set up roleplaying scenarios in game and wrote stories on their website forums. Initially, they were not a guild, but an association of players from many guilds. Not long after they guilded in game, Laveaux stopped playing. From what I understand, Kakari was playing infrequently and that left everything to be done by Kenkaishin/Nogog. Many of the people associated with CoN were from other guilds and did not join CoN and it quietly passed away. I am certain Kenkaishin could provide more perspective on this, as it was his guild.
