Actually, I have a thought.
Nasrin began this fellowship of unofficial knights of an old blood oath that I decided to work with when I worked on Rena Goldswith. It's basically a group of old houses that answer to a call of greater import than the Serenian kingdom itself, dating back to a time in which the union of man and elf was forbidden, and that the knights were in the service of the elf in question, rather than the bigoted king who forbade association with his family.
They are unofficially knights, perhaps knight's templar may be more accurate. They have Houses, estates of some note. Rena is officially the Magistrate of the Terrin Mountain Mines in the town of Zefras. The others...I forget, actually. Nasrin would know, and maybe has a full list. I know the positions weren't all filled.
