#truth fmab

So basically, Sirius and Harry were isekai'ed to FMAB through the Veil of Death, which wasn't actually a murder portal but really a fake Door of Truth.

Truth is mildly annoyed that they're there (not together tho) because they didn't commit the taboo, but they're really not supposed to be there and he can't let them go without a price. He offers both the option to go back, for things to be exactly as they left it, or for him to "improve their lives." If one goes back and the other didn't, then the loss of the other would be the price.

Sirius gets the option to live in peace with his goddaughter without anyone trying to separate them, and he jumps at the chance. His price is that he's permanently stuck as Padfoot.

Harry is a bit more complicated. Voldy's horcrux is also there, and Truth isn't about to get that away. He's also not going to lie to Harry about what it is, so she learns about the horcruxs early. Truth offers her going back or a normal life.

Harry asks what would happen to Voldemort. He would win, Truth explains, because she wouldn't be there to defeat him. Harry resolves herself to go back, but Truth points out that that's not what she really wants. Harry wishes she could have both.

Truth seems to consider this and makes her an offer. The price of this offer is her memories and her magic. But magic and alchemy/alcehestry are different, and Harry gains all the chemical knowledge of alcehestry.

She's actually going to get her memories back during the Final Day! but not her magic.
