In the meantime, she had to help her subjects protect the Holy City!

Lady Farah, her heart heavy with the weight of impending doom, raised her hands to the heavens.

"By the grace of fortune, let resilience be our shield and valor our sword!" She intoned, her voice carrying the power of the divine.

Without being noticed by the defenders of the city, a golden light cascaded from her palms, washing over the city and its defenders.

The Holy Knights felt a surge of strength, their fatigue replaced by a renewed vigor. A new barrier was created, bolstered by her blessing! Furthermore, it held firm against the barrage of the Demons!
