Indeed, my southern neighbor, the Council of Wyrms. What a game that was...
I certainly don't know of any that lasted longer, but I haven't played many multiplayer games.
Teraswaerto, I actually had that site, in the Dawnstrike game we played together. It was very, very nice (though I didn't have the blessings to allow the Sidhe to work very effectively against Jurri's Caelum, unfortunately).
