Square Enix will be opening up a new area, Outer Ra’Kaznar, in Final Fantasy XI‘s upcoming version update. Nothing is known about the new area except that the developers have recently finalized its placement of monsters. It will likely have something to do with Seekers of Adoulin endgame and mission-related content, both of which SE is continually updating.
The area is likely related to a currently locked zone, which players have described as having an entrance resembling that of a Borg cube from Star Trek. No large screenshots of the new areas are currently available.
The upcoming version is scheduled for February 18th, one week from tomorrow. You can check out an extremely low-resolution shot of the new area below.
