Snowballs in Hell

When Hell freezes over it's up to Muriel, Hell's most awesome princess, to set things right.
Hi, I'm Muriel, misbegotten daughter of Satan, and once again, my life is in turmoil. An enemy left a curse on my mind, one that makes me afraid. Completely unacceptable, but in order to charge my magical batteries and remove it, I have to do something awful-betray my beloved.
As if having to participate in a threesome isn't traumatizing enough, Hell has frozen over, and although Hades looks pretty in a blanket of white, the repercussions are severe.
Time to grab my sword and feed it some fresh demonic blood. The fate of not just Hel, but the world depends on me. Can I do what it takes to save the world?
