Clerics of Northshire

The Holy Order of Northshire Clerics was an order of priests within Northshire Abbey before the First War. The priests of this order helped to spread the message of the Holy Light to those of the Kingdom of Azeroth. Though, during the First War, these priests had offered aid to the Kingdom. Under the leadership of the Archbishop Alonsus Faol, the brave priests of the Holy Order fought valiantly with healing magic and devastating powers of the light. Though, they were not battle-ready in the slightest, and were slaughtered by the Orcish Hordes.

After the victory of the Orcish Horde in the first war, Archbishop Alonsus Faol, along with his apprentice Uther the Lightbringer trained a new breed of holy warriors, those who had unmatched ability in wielding of the light, as well as the combat prowess of a warrior. Thus sparking the birth of the Order of the Silver Hand.

Currently, the Holy Order of Northshire Clerics has been disbanded in place of the Order of Northshire, a collective of Clerics, Priests and Paladins.

Speculation
It is believed that the Holy Order of Northshire Clerics once believed in a deity, and had a monotheistic belief in a 'God', and that perhaps the world was made by one all powerful being. Multiple accounts of members of the Order can be found referencing God, or the Angels, as well as references to Hell.
