Paladins are champions of order, crusaders who oppose the burning crusaders of the Burning Legion, a vast demonic army of demons created by the fallen titan/world Sargeras to scour all creation.
Paladins are a holy order of warriors whose purpose is to defend and shepherd the war-torn populace of Lordaeron. The Archbishop Alonsus Faol perceived that the pious Clerics of Northshire, who suffered such terrible attrition in the First War, were ill-suited for the dangers of combat. Along with many of the surviving Clerics of Northshire, he sought those of only the greatest virtue among the knighthood of Lordaeron and tutored them in the ways of magic. Led by the crusading Uther Lightbringer, it now rests upon these Paladins - christened the Knights of the Silver Hand - to heal the wounds sustained in combat and to restore faith in the promise of freedom from Orcish tyranny.
