While running around on Test yesterday, we were notified by Kuulei that there was a new guild hall available for touring on the Antonica and Commonlands guild hall bells: Restored High Keep.
Not much is known about it yet, aside from the fact that it is the entirety of the High Keep zone. Afista of EQ2 Design Gallery has posted images of the entire place over on her site. We did ask Senior Producer Holly Longdale about it and she responded "It's coming out the end of April. We're working on the details of how it's acquired at the moment."
Could it be a Marketplace-sold prestige guild hall, akin to the Palatial halls on EverQuest? Looks like we'll find out sometime in April! In the meantime, you can tour this hall on the Test server, but the exit doesn't function so have your Call to Home spell ready to get out!
