Sheogorath. The Prince of Madness. A man who has grown bored with his own world. When he brings his insanity to a land of peace, the Royal Sisters find themselves thrust into his world. A land of perpetual war and chaos. Survival is the least of their problems. If they are to find each other and return home, they must call upon the aid of a hero of prophecy. A hero that is said to rival the power of the sun itself. They must find him and prevent the destruction of two dimensions in the process. Little do they know how mentally unequipped this hero will be for both of them...
(The Dragonborn in this is going to be based on the default Nord look to make the story flow a little better.)
(And just as any author on this site will tell you, be gentle with me, this is my first fic, so there's no guarantee that it will exactly be perfect.)
