Have you ever thought where they are now? Well, today, I'll answer your question:
Where are the current locations of the Deathly Hallows?
1. The Elder Wand
The Elder Wand was in Dumbledore's hands for most of the series, then Voldemort's in DH/DHP1. When Voldemort dies, Harry takes it and puts it back in Dumbledore's grave. So, it's in Dumbledore's grave, right?
Well, I have a feeling that Delphi, who looked up to her father, probably wanted to continue Voldemort's plan to become the most powerful dark wizard of all time. This is why I think it is possible that the wand may currently be in Delphi's hands. If not, it's probably still in Dumbledore's grave.
2. The Resurrection Stone
It did get lost in the Forbidden Forest, but who was in the forest? A lot of people, but mainly Voldemort. That's right, I think Voldemort may have found the stone, and when he died, it may have gotten passed down to Delphi. But honestly anyone who was in the Battle of Hogwarts could've found it and passed it on.
3. The Cloak of Invisibility
The Cloak of Invisibility is in Albus's hands currently, we know from Cursed Child, but honestly, I think he and James would "share" it, they wouldn't actually share it though, Harry would make them share, but probably James would pass it on to his son because he is the eldest. Maybe Albus will pass it on to his son, but I think it's less likely.
So there you have it! The current locations of the three Deathly Hallows :)
