Blood

Queen Guinevere's Spirit Pressure seemed to make the skies bow down. It was only at this moment that the people of Camelot and the Demon Empire realized that the strongest mage of Camelot wasn't The Pope, nor was it Arthur, nor was it even Mordred… 

It was the Queen of the people. Guinevere Pendragon. 

"Hoho! Good! The more, the merrier!" 

City Lord White's laughter continued, brandishing her hammer to smash toward King Arthur again as though she hadn't sensed Guinevere's presence in the least. 

Sharp, icy winds spun around the Queen, her black hair rapidly becoming coated in a thin layer of ice. In an instant, her tanned skin and black hair became as white as snow, her eyes becoming such a pale shade of blue that they too seemed to become white. 

Several javelins of ice formed to her back, shattering the sound barrier as they shot forward.
