Demios and Elleen experimented with all methods of murder: slicing, crushing, disemboweling, and more. They found pleasure in their twisted trials, and there were no shortage of subjects in those who intended to stop the twins. They slaughtered everyone at the academy, then in their own town, then in the entire kingdom. Yet their bloodlust had not been satiated, so they continued to new lands in search of new prey.
