Currently I have three chapters of knights, although I am considering more ...
1. The Knights of the Aver River ... this is a home brew chapter that I created in conjunction with my Aver River Regiment. In the meantime, here is a bit regarding my home brew knightly chapter called The Knights of the Aver River ... these knights pattern themselves off the Empire's Reiksguard in their manner of armor and weapons, although wear different colors, the black and yellow of Averland with blue highlights. Their founding member was a man named Siegmund von Friedlichwald. Seigmund grew up in the small lumberjack town of Friedlichwald that is located in the forest between Averheim and Verborgenburg, but grew up with dreams of becoming a Knight. Eventually he traveled to Altdorf where he joined the Reiksguard, and soon there after "retired" from them to found the Knights of the Aver River. This knightly order patrols from just within the sight of Averheim, along the Aver River to the Moot, along its southern border to the Blue Reach following it all the way to World's Edge Mountains. Their Chapter House is located at Verborgenburg in Averland, a town located in the hills between the forest and the Moot, and directly across the ford that is near Scheibbs in Stirland. The Knights of the Aver River have an agreement, along with the Aver River Regiment, to aide the Moot in times of need, and patrol along it's southern border accordingly so as not to interfere in the day to day happenings of the halflings who live in The Moot. (6 figures.)
2. Order of the Golden Lion ... potential fluff for my unit to follow. (6 figures.)
3. Order of the Black Bear ... potential fluff for my unit to follow. (5 figures, and will likely add 1 more.)
Considering having a unit of the Blazing Suns, maybe a unit of the Knights of the Broken Sword, and perhaps others.
