...eventually. I might wait to see how the Season Six premiere plays out first, because the plotline's kind of dependent on if Willow uses a spell to bring Buffy back. Anyway, I have the general idea for the main plot, and the W/T subplot. Actually WRITING it will be the hard part, and I still might not do it, but...tell me what you think. (And if anybody knows the names of Tara's parents, let me know, 'cause otherwise I'll use the ones that I made up.)
"LOOSE ENDS"
A Buffy fanfic
PLOTLINE: When Willow does the spell to resurrect Buffy, her magic proves to have dire consequences. The spirits of the dead are called forth from the heavens, doomed to wander the earth in fear and agony...unless Buffy Summers is returned to the netherworld.
W/T SUBPLOT: Meanwhile, Tara learns of Willow's forays into the dark arts, and reveals the truth of her mother: Angela Maclay knew a Slayer when she was a teenager. (This is maybe two, three Slayers prior to Buffy's calling). The Slayer had been killed by a demon. Furious, Angela went down the road of the black arts to fight and kill the demon. But twenty years later, that magic came back to haunt her. The spell she'd used was so powerful that traces of it lingered on her body. It caused pain and death to those around her. John Maclay decided that Angela was a demon, and placed her in solitary confinement. With no one else around to affect with her "bad luck," the magical residue fed on Angela herself, draining her of her life force until she died - when Tara was only 17. Tara had been born with magic, but she'd vowed never to use anything other than white magics. She knows that if Willow continues to go down the path of black magic, she will eventually die from it - just like Tara's mother.
