Twilight Of the Gods
The Tarusian Knights are an elite cavalry group that operates independent of the normal chain of command. Usually the Knights are only held accountable to the Empress and her top generals, and even then they are typically allowed to work autonomously.
The Knights act as elite shock troopers as well as infiltrators and saboteurs. They are often called upon to weaken the enemy in the days and weeks before a pivotal battle and then often lead vicious flank attacks during the fight itself, ensuring a Tarusian victory.
The symbol of the Tarusian Knights is a serpent wrapped around a shield.
