But Dead Girls Can't Curse

Auror Harry Potter is looking into a new dark wizard, one rising worryingly fast. On the other side of the planet, Severus Snape blinks open somebody else's eyes and a strange man calls him 'Carmilla'. [Genderbent Snape. Canon pairings, some blink-and-you'll-miss-it Harry/Draco implications. Some completely non-canon-compliant magic. ABANDONED.]
