Notes
The Knights of Iron is the official name of Gaerdal's priesthood
The crusaders are very similar to a gnomish form of paladin, and may not be multi-classed
Gaerdal's crusaders have a great dislike for priests and worshippers of Baravar (god of illusions)
Gaerdal is revered by many, but has few priests
Background
Gaerdal, the most stern and serious of gnome deities, is the patron of warriors and protectors of gnomish communities. As such, he is honored in some manner by nearly all good-aligned gnomes, and one or two crusaders will be found in most good sized settlements. He has no formal church as such: each Knight of Iron (as they are called) advances in his service through prayer, fasting, and meditation. When a knight commits a serious transgression, he (or she) must seek out the nearest higher-level Knight of Iron, and atone with a quest of that knight's (and Gaerdal's) choice.

Gaerdal's knights are expected to defend their people against any threat, even at cost of their lives. They are typically served by one or more fighters in the service of Gaerdal, and will occasional build and maintain stone forts on the borders of gnomish lands. Failed Knights of Iron are still welcomed by their people, but are shunned by all in Gaerdal's service.
