An unofficial arm of the Church of Law. The Unblemished are soldiers and unsanctioned guardsmen in towns or cities where Law holds sway. Because of the church's annual receipt of tithes from the these troops tend to be very well armed and trained. The Unblemished will typically be armed with mace or club, fighting spear, and dagger; they are almost always clad in plate and carry shields.
Sometimes these men and women, almost always humans, operate with the blessings of The Nine and the leading members of the local clergy. Other times they operate independent of the local clergy under the command of a Cleric, who may or may not answer (or at least confer) with the local clergy.
The Unblemished always cover their faces when in uniform, communicating only in the Lawful alignment tongue. In stressful situations, any being unable to communicate in same will often be detained. The Unblemished are very often fanatical in their devotion to The Nine and will usually err on the side of dogma in pursuit of their duties. These fanatics are often rigid and unyielding in their faith, even to the point of great personal cost.
Unblemished soldiers are always found preferably in groups of nine or multiples of nine. In such a case there will be one soldier bearing the sigil of one the deities on his tabard, all of The Nine will be thus represented. In smaller communities where numbers are lacking they will resort to groups of three.
If your campaign uses paladins, this is a great source for them.
