Could somebody please explain this thing I've heard about the citadel's structure being like Xen? --Alph Tech STUART 06:43, 18 Dec 2005 (PST)
I highly disagree. While the citadel architecture is more blocky, the xen architecture is much more round. I don't see how they have much in common at all.
I also disagree with not being able to find humans in xen. HL+OP4+BS showed that materials and beings from earth were sometimes teleported to xen, and that xen has a breathable atmosphere. Of course, 8 scientists being teleported into the same tiny floating island is unlikely, so it should be used sparingly. User: Nih
