Antonia Bayle, the high-population role-playing server, is having another seasonal role playing event.  Gnobrin reports on the official forums : 

Not to be outdone by this year's Festival of Unity, the less good'ly inclined guilds of the Antonia Bayle server have set aside their schemes and plots to organize the single largest accumulation of dark intent that Norrath has ever seen!  Behold, the Festival of Discord!  Drink deep of this goblet of ill intent as you joust, behold the always "alluring" Troll beauty pageant, sup deep of the sacrifice and torture of those of good deeds as well as party the nights away!  If you take pleasure of evil deeds or if you're simply curious (but hopefully fleet of foot to escape, if need be!) be sure to travel to the Commonlands on the Antonia Bayle server, starting Sunday October the 12th, 2008 and stick around until the closing "ceremonies" on Saturday October 18th, 2008.
