Knights of the Chalice
Knights of the Chalice are a unique order of paladins and knights who battle demons in Mendev. Some of them actually travel the world to rid other places of demonic influence, such as the Tanglebriar in Kyonin. But most members of this order remain in Mendev to battle the growth of the Worldwound and its minions.
Members of this order come from the cavalier, fighter, and paladin class. Some of them are clerics of Iomedae or Aroden, and all of them are priests of those faiths. Inquisitors rarely become Knights of the Chalice but those who do comprise the bulk of those that wander from Mendev. All Knights of the Chalice vow to battle demons and other evil outsiders wherever they are encountered. They are trained to fight these foes to the exclusion of others and can expel them from the Material World with mere blows from their swords. They become beacons of hope and valor, and their holy aura’s strengthen their blows and their allies in battles against demonic taint.
