Well that's what it looked like!! It did! Right down to the architecture!
Of course WoW shamelessly ripped off or homaged the Minbari, they created a whole freaking race of Minbari and their "crystal cities". So these little bridges were built long ago.
The Mantid storyline does seem to pretty much be the Wraith one too. A insectoid species that awakens to kill every x amount of years woken early by the appearance of travellers from afar...
