Under cover of shadow and spell, pieces of parchment and signs bearing the same message are placed up all around Amia and the main land of Faerun. They would be seen in places such as the frontier of Amia, the outskirts of Bendir, the Bramble Woods, Sandy Beaches, the Quagmires and outskirts of Kohlingen. On the main lands they would be found in Ruathym, one near the shipdock outside of Wiltun, Caraigh's forests, the Mills the areas of the Khem desert, the frozen lands outside of Brogendenstein and Endir's Point and the Frozenfar. Still more could be found tacked up along various roadways. There would never be more than a few signs or posters to any area, so as to not clutter the land with such things. Curiously most major cities such as Cordor, save a solitary poster on the lightpost near the cart to Bendir, and Kohlingen and the dwarven city of Brogendenstein, and also Amia Forest, have not a trace of these postings, instead it would seem they were placed safely back from the borders of their jurisdictions without intruding into their territories. If one were to catch a glimpse of whoever placed a poster or sign, they would only be able to discern a shrouded, shadowy figure with it's face hidden and blackened from view.
// PMs would be the obvious way to go.
