This story pertains to the sudden and wildly unexpected surprise of Lestat de Lioncourt and Magnus Bane allying themselves to find one of Lestat's lovers groveling in the heart of seedy New York City. I recommend you assume that The Mortal Instruments and The Vampire Chronicles are in the same universe. If you want my rationale on how they are, just ask. And -- of course. The characters belong to the respective owners.
