"Few locations on all of Gaea are as heavily infested by restlessness as Zanarkand, the ancient and long-ruined metropolis of Spira. A millennia has passed since whichever events cast the city into ruin, and many of the restless spirits here are at least as old. Undertaking a foray into such a place as killed many a treasure-hunter or well-meaning archaeologist, and I would not be surprised to find them wandering her avenues and halls, either."
-Excerpts from the Diary of a Shade.

"You can't just come wandering in here from Ultima-knows-where and order us to stop our dig, human!"
"I believe I just did, Master Archeologist Brunel."

The Nu Mou growled at the young man who had wandered into their camp, in robes as black as the night, with a silver eye blazoned across his back. "If you think we are going to pack up and leave after all we've sacrificed to be here, you have gone quite mad, Eli Sharona."
"Nobody said pack up and leave. I said stop digging. It's more than old machina killing your men out there. The dead of Zanarkand are restless as any I've ever seen. Stop wasting men and swelling their ranks and let me put an end to it."
"... Fine. We'll give you five days, and then we're digging again."
"Fine, but if I decide five days aren't enough, I'm sending you all packing myself."
