The Hall of a Thousand Mirrors

Without the protection of the shared dreams of the lizardfolk, the dragonborn of Arkhosia had little protection against the corrupting power of Masvirik. Clan fought against clan, and those that opposed Masvirik had to focus nearly as much upon traitors within their own ranks as they did the armies of Rhashaak.
At first, the dragonborn would look at someone who fell to Masvirik’s influence and declare this a personal failing—the role that pride and dedication played in their psychology and culture would allow little else. Still, they recognized that the process was not instantaneous and that there was no shame in an individual strengthening their will against Masvirik’s influence. To this end, they built sanctuaries like the Hall of a Thousand Mirrors where those who showed signs of Masvirik’s influence were given support in fighting against it.
Today, the Hall of a Thousand Mirrors sits underneath a recently built House Jorasco enclave. The hall consists of a labyrinth full of magical mirrors. Few who have entered the labrynth remember more than seeing their reflection in one of the many mirrors. Regardless, it is believed that they leave the labrynth cured of the curse or madness that afflicted them. Some, however, say that the people that leave the Hall of a Thousand Mirrors are not the same that entered it...
The dragonborn have lost these facilities to history, but—if they were recovered—they could change the balance of power between the dragonborn clans and the Poison Dusk.
