Sylvia certainly hadn't expected to have the harpy she attacked cause a crater, but it was still pretty cool. She then turned her attention back to the battle at hand, and soon enough, there was only one harpy left. She managed to land an attack on the foot, but it wasn't much. 

Sylvia could only watch as it flew away from them and started...singing?

Her mind immediately recalled Greek Mythology...

Of course...just as she was trained by a Satyr last night, of course she would encounter something that could be akin to a siren! At least, that was her guess. 

She closed her ears with her hands, with her staff in the crook of her elbow, and she called "Get ready to restrain anyone who starts acting weird!"
