The Fane of Kaprima (FoK) dungeon was removed from the game by the patch in september 2013 yet, which brought us four new dungeons: Wonderholme, Kezzel's Gorge, Shattered Fleet and Channelworks.
In 2014 the dungeon was back for a short time to clear, as an event, but it became unavailable again before the Fate of Arun update.
As planned, FoK will be back soon, as lvl65 dungeon, with changed mechanics, new minibosses, changed design (last room), and map (one way instead of two).
Here is a video of the lvl65 FoK, from engineer's PoV:
