Chivalry and Valor

Suddenly, the Knight warrior decided to stab himself in the stomach as the raging troops of enemies charged through the destroyed walls, causing gasps of shock and disbelief to ripple through the remaining defenders. 

The knight quickly began to chant an ancient spell, invoking the formidable powers of their world.

"Oh, the old gods and the new... I offer my life in exchange for power." he spoke, his voice resolute despite the pain.

"Use my life force to create an impenetrable wall that protects my home." as his words echoed across the battlefield, the air crackled with energy.

The knight's life force surged forth, intertwining with the incantation he had spoken. A vibrant green aura erupted from his body, expanding outward and enveloping the fortress.
