Dumbledore speculated that Voldemort’s actual goal was to have a Horcrux from each founder. But could he have achieved this goal?
In this chapter, Bellatrix panics when she thinks that the trio has broken into her vault at Gringotts. We speculated that Voldemort might have instructed Snape to put the sword into the vault, and that his reasoning for this might be that he wants to make the last relic of a Hogwarts founder into his final Horcrux. But as Hermione tells us, the sword is impregnated with basilisk venom. Of course, basilisk venom destroys Horcruxes. Therefore, would you be able to make the sword into a Horcrux? Or would it backfire on Voldemort?
