The heavy horse of the Duke of Bravant.
First, the Gensdarmes of the Guard, led by their colonel-in-chief General Epinoy
Red with yellow (gold for officers of course) turnbacks. Bays, except the trumpeter on a grey.
Next in precedence, the Regiment St. Laurent.
Finally, Regiment St. Urbain.
Yes, they are "Saint Urbain's Horsemen" -- I never could resist a bad pun. And yes, St. Laurent ("La Main") is also a Montreal street.
I also really like their commander, who is from one of Pendraken's commander's singles.
