Ok, so the main things to research are :
The Ordning, The Nightstone, and the Ostorien Artifact. At this point, I wonder if the Nightstone is a part of the Ostorien Artifact. I will let all know what I find.
Also, does anyone know of a recent event called, "The War of the Silvery Marches"? There was an act of betrayal that occurred here and it's end may have played out in the town of Nightstone.
