Two guards talking seconds before attack
The Dun Tynne Guards were knights of Toussaint who served Lord Roderick at his castle, and its surroundings, along with mercenaries from Nazair. The captain of the guard was the lord himself, and the unit was almost entirely above the law. Most of the guards died when the castle was assaulted by the Ducal Guard led by Damien de la Tour.
Those who did not, either managed to escape somehow or ended up in prison shortly after the attack.
