Bastion

"Bastion."

With that word, whispered in wonder, the spell resolved. I looked up, my fear, embarrassment, and anxiety forgotten, as mana arced from the rims of the titanic magic circles surrounding our sparring ground, converging in a small, pulsating dot five hundred feet above the earth.

The mana began to expand outward, flowing like liquid sunlight around an invisible sphere, forming shimmering curtains of golden light that extended toward the ground. Delicate arcs of energy coursed through the membrane of Protection Magic like veins, and a soft, humming resonance vibrated deep within my bones.
