Martial Tradition: Paragons of Honour

If every unit from your army has the IMPERIAL KNIGHTS keyword (excluding units with the AGENTS OF THE IMPERIUM or UNALIGNED keywords), then after you have sworn 2 Oaths for your army, you must, if any models in your army have this Martial Tradition, swear one additional Oath. This Oath applies to all models in your army with this Martial Tradition.
