Concept: A female professor of Archaeology discovers ancient artifacts that change her into an impressive warrior.

Background: The artifacts were a warrior's gifts from an ancient Egyptian prince for his bride.  Whatever happened between the two is a mystery, but when our heroine, Dr. Henrietta "Hattie" Falcate, discovered them and removed them, she gained their mystical power and woke the prince from his temporal stasis.  The gifts, he told her, were for his bride and she possessed the reincarnated essence of his long lost love.

Hattie was having none of it. She fled the chamber and returned to England.  However, the prince followed her from the astral realm and is insistent she give herself to him.  He pesters her (Bad Luck) and sends his agents after her to return her to him (Enemy).

Hattie is stunned by her new found abilities.  She has the athleticism of an Olympic champion and can summon her crescent blades from thin air.  She researched the prince and discovered that he was the founder of an ancient death-worshiping cult, where female "priestesses" were the main assassins.  Their symbolism was the crescent moon and as a point of defiance to the prince, Hattie took the name Sister Moon and began to use her newfound abilities to save lives, rather than take them.
