It's another server we bring up just for quests.
Usually it's running a copy of West or Central, depending on the GM's need. It's not for general use, but is rather intended to give GMs a reduced-lag environment for running quests.
You can connect to it at quest.layonara.com:5121 or 69.80.192.72:5121 but again, only if directed by a GM to do so for the purposes of a quest.
One thing to note: if the quest server is running the West module, you must log out of West and into Quest. If it's running the Central module, you must log out of Central and into Quest. It acts just like any of our other modules, and you will be booted out if you try to log onto the wrong server.
