Lucius Malfoy has a conundrum. The Dark Lord admitted at his resurrecion that his father was a muggle. Since then his social status has sunk beyond the depths he had suffered since the First Blood War. His businesses are teetering on the brink of insolvency and the Malfoy vaults are being leaned on as the Dark Lord's personal pocket money. The last straw is that he's completely lost interest in anything other than a thin crust of pureblood supremacy, is obsessed with James, Lily and Harry Potter and is actively trying to wipe out Pureblood families.
Solution: he and Elizar Nott have the wand of the darkest of all dark witches, Morgana le Fay, and the means of resurrecting her. Replacing the devil they know with the devil the don't is an acceptable risk.
However, the resulting resurrection produces a particularly capricious barely-adult dark lady.
Lucius is reduced to being Morgana's maidservant and Narcissa is promoted to run Malfoy Manor as the Dark Lady's seat of power. Draco is reduced to a barely-acknowledged minion. And what's this about the Potter family's scion, enchanter and artificer. Does a Dark Lady need a consort? Morgana decides to discuss this with Lady Lily over tea... once Lucius has poured for them and kissed Lily's signet ring on bended knee.
Going to get writing this either later today or tomorrow (it's a HEMA night tonight so swords out.)
