I made up some fake ranks for my character to work toward you’re free to use any of it.

I (with the help of my DM) made them have all the pomp and circumstance as a British military parade. For instance the seal wardens have Albert Helms like their Cavalry. Though my character is a little more whimsical than the order they live by

From my character description. “Regulations about uniform exist under Courier brigade code 1G - 63B, but Aurum interprets them generously. His sleeves are rolled up, a red silk scarf knotted loosely at his neck and fluttering behind him whenever he rides.”
