It's interesting how much the book slags Terok Nor, really. *lol* Prynn disses it, Picard disses it, the Militia guy disses it.... doesn't anybody like the poor station?
Well, that was always kind of the idea behind DS9 -- that it was an oppressive, alien environment that was uncomfortable for the Starfleet characters to be in and difficult to adjust to.
Which is ironic, as I often found the DS9 sets quite cozy-lookin'.
But Cenn has had a longstanding dislike of the Terok Nor design, going all the way back to his first appearance in Worlds of Deep Space Nine
