How would you guys feel about a guild party? We could hole up in a cave or a bar, even make it a kind of a headquarters. If anyone would be interested, the details would be given to you via ingame mail, but you can all expect a roast with some nice buffs, some belcher's bluff tables, socializing, perhaps someone playing on an instrument in the far corner so you don't hear them if you don't want to, maybe even a bonfire with karma/magic find buffs.
And of course, pre and post events, like jumping puzzles, dungeons or a good old-fashioned dragon slaying.
