... Though my time within the lands of the Lady has come to pass, my time serving her has not. By my hand and her mercy, my honour shall be restored, even if it is to be my final quest in this life…”
The Exile’s Vow is a Chivalrous Vow, as described on page 108 of Forces of Fantasy.
A model with this Chivalrous Vow has the Stubborn and Veteran special rules. In addition, a model with this Chivalrous Vow does not have to make a Panic test when a friendly unit with either the Levies or Peasantry special rule is destroyed whilst within 6" of it, or when it is fled through by a friendly unit with either the Levies or Peasantry special rule.
