Previewing halls

Am I able to preview halls before I buy them? I want a specific one but don't know what it's called, if not, then can anyone tell me what the hall that looks like a chineese fortress is called? It is very big and has tons of rooms. Thanks

Yes, you can preview all guild halls.

Talk to the "Canthan Ambassador" located in Lions Gate, Kaineng Center, Kamadan or the Temple of Balthazar, and he will give u the option to preview guild halls. Here is the GuildWiki link all about Guild halls, at the bottom are links to all the different halls with pictures::

Oh, and the Imperial Isle (factions) is most likely what you are thinking about, the only close to oriental flavor one is Warrior Isle (Prophecies). Hope taht helps out!

cheers.
