The first one Allen Grey of CoD clued me in on. Apparently it’s tied to the new winter motif of Dereth — a scouting party is lost while looking for a lost city and the players (those high level enough to go through the portals anyway) are off looking for them. It’ll be interesting to see how AC handles a cross-shard quest — although not quite on the scale of UO’s Zog Cabal (urp) Followers of Armageddon quest, any plot in an ORPG is something to be carefully nurtured.
Of course, Turbine may be a bit busy, since Dr. TwisTer found a dupe. True to his word, he hasn’t posted it. Yet.
