Remember
With a final pulse of light, the magic circles vanished and the Ice Spirit manifested in the clouds above, finally taking on solid form. Snow, ice, and storm clouds all flowed together to give the elemental form, condensing into a five-hundred-foot-long serpent. It slithered through the air like a water snake in a river, coiling tightly around one of the main towers of the central citadel.
The fortress's defenses came alive around it, and arrows, spells, and streams from the magical artillery collided with the spirit in blinding explosions of light and mana. It hissed furiously and tightened its coils, shattering the tower and defenders atop it.
