Kace was glad that he was semi on the right track. He heard the other student's answers as well and they all seemed logical. He heard the professor move on and wanted to know what the differences between the two. Kace snorted and thought it was obvious but he heard student's answers and apparently not. He raised his hand and said, "Professor I agree with my buddy Adi over here. The cold ones are formed with a potion, there bodies are laid out there to be freezing cold, hence the name "The Cold Ones" and the Skygge is formed by freezing of the heart. Which I think is very cruel to have a cold heart." he shrugged adding a little humor in there.
