The Knights of Templar might be considered a legend in today's conspiracy ridden world, but they were actually a real thing that disbanded over 700 years ago.

Sergeants were from non-noble families and served as light cavalry officers, the main battle support for the knight. In addition, sergeants had important skills and trades such as blacksmithing and construction, and often oversaw many of the Templars' European properties. Sergeants dressed in a black tunic and a brown mantle, usually with a red cross.
Chaplains were ordained priests who heard the knights' confessions and granted absolution for sins. Chaplains were answerable only to the pope, rather than to local clerics or bishops.
The presiding officer of the order worldwide was the Grand Master, an office held for life. Each local region had its own master and commander, assisted by a seneschal, who oversaw the movement of the army and its supplies; a turcopolier in command of the light cavalry; and a marshal in charge of light arms and horses.
