The Province of Amalur
Domains of Dread
In the remote corners of the Shadowfell dwell the horrific demi-planes ruled over by accursed beings of terrible evil. The best known of these is the valley of Barrovia, overlooked by the towering spires of Castle Ravenloft and ruled by Count Strahd von Zarovich, a vampire lord.
Beings of the Shadowfell called the Dark Powers created these domains as prisons for these dark lords and through cruelty or carelessness trapped innocent mortals within these domains as well.
