This article refers to events, personae, items and activities that are involved in the Guild Halls World Event, which went live with GU48 on 9/3/2008, and ended with GU49. The events and activities described here are no longer in the game.
This is the template that makes the little world event bar for the Guild Hall Construction World Event stuff, because I'm a dork and used {{ghwe}} for the rewards bit for the 32 quests.
