Titania

The two threw their cloaks, revealing their actual appearance. Sylvester rushed to the other revolutionaries trying to help those above the wall from blocking the prince's way. He cut them all while Titania flew into the air and kept making the revolutionaries float with her. 

"I'm still nauseous, and I might vomit a little. Just stay out of the way." She said to the Archduke, which made him laugh. 

"Yes, my lady." 

Sylvester unsheathed his sword and made a whirlwind using his sword. 

The whirlwind caused the revolutionaries to back away as they saw how strong the Archduke was, not knowing that he was the Alynthian Empire's Archduke. "Titania!" He called the fairy's name, and Titania summoned a spell she learned from Nathania herself. 

A smile forms on Titania's face as she throws the colossal ball of accumulated air that could slash anything on its way. "Move!" She said as she threw it in Sylvester and the revolutionaries' way.
