After a long and treacherous journey, our Hero finally arrives at the Dark Lady’s castle only to find himself being asked for help.

The queen of demons however argues that this war has made the human society band together as one and showed empirical evidence how it has increased population, increased production, boosted economy and improved society overall. Furthermore, she explains to the Hero that ending this war will result in a civil war that will produce more bloodshed than there ever was.
