The first Order of Battle Nuns was started five hundred years ago back when the Church was aiding the Kingdom of Nurian to fight off the Qynari heathens. After years of bitter fighting against their necro-melded  armies, the Qynarate held the upper hand. They were poised to sweep over Berthold's Pass and into the Nurian heartlands, whereas the Nurian-led coalition army was mostly put to flight in a previous battle, leaving only a small handful of defenders to hold the pass and keep the enemy at bay.

With the defenders was a 12-year-old peasant girl named Therese Olon. (Olon was a nearby village.) On the day of the battle she stood forth, and eyewitness accounts say she was filled with the Light of Salvation and, wielding a mace made for a much larger man, enabled the defenders to beat back their gruesome enemy, thereby saving Nuri from certain destruction.

After the battle, Therese went on with the army for another four years, culminating in yet another victory and the sacking of the Qynari city of Akarim Gel, thus putting an end to the threat. In the last battle she was fatally wounded, but she had gained a following of other women and girls to carry on her legacy.

That following became the first Order, the Sisters of Unfailing Humility. Therese was canonized and the Order recognized by ecclesiastical authority a mere ten years afterward.

All Battle Nuns are members of one of the militant female orders of the Church. Examples include the Little Sisters of Mercy and the Most Humble Daughters of Her Supreme Mitre.

Orders of Battle Nuns specialize by weapon type. A Nun of a particular Order may only use weapons of that Order's chosen type, which must be decided at character creation. (Players are encouraged to create Orders to which their Nuns belong.) A Battle Nun may use any sort of armor, but no shields.

A Battle Nun gets some recompense for her restriction in weapons. At level 3, her weapon counts as magical for the purposes of damaging enemies that can only be hurt by magical weapons.

At level 6, a Battle Nun rerolls any 1's she rolls for damage with her chosen weapon. If the new roll is also a 1, it stays.

Turning Undead: A Battle Nun may Turn Undead as a Cleric 2 levels lower.

Reaching 9th Level: On attaining 9th level, a Battle Nun may establish or build a convent. So long as the nun is currently in favor with the Church, she may buy or build a keep at half the normal price due to ecclesiastical intervention. Once a convent is established, the nun's (now abbess') reputation will spread and she will attract 1st and 2nd level followers of the Battle Nun class (numbering 5d6 x10). They are completely loyal (never checking morale).
