Was Ariana Dumbledore an Osbcurial?

Potterheads have thought about many theories behind the whatnots of JK Rowling’s magical universe. Now, maybe we know what happened to Ariana Dumbledore.

We’ve all gone down the rabbit hole of tumblr, Reddit, and many other fan forums trying to solves the puzzles JK Rowling left us. Time-traveling Ron is still my all-time favorite fan theory. But with the release of Fantastic Beasts, fans are making connection to the mystery about Albie Dumbledore’s sister, Ariana.

Reddit user amightyslytherin has this to offer the fandom: 

Ariana, Dumbledore’s sister is an obscurial. We learn from fantastic beasts that an obscurial is a witch or wizard that is repressing their power. That the power is manifesting itself in the form of a dark cloud, known as an obscurus. Usually this power eats away at the witch/wizard and kills them around or before the age of 10. This will come into play soon in the theory.
We know from the main series that Ariana was “attacked by Muggle boys who saw her practising magic. This left her traumatised to the point of rendering her magical abilities uncontrollable” at the age of six. Maybe this didn’t render her unable to control her power, but afraid to use it again for fear of getting seen. Soon after, Ariana’s father, Percival, supposedly went after the boys and killed them, and thus went to Azkaban. It’s more likely that Ariana’s obscurus attacked the boys, and Percival took the blame to protect his daughter. These are the perfect conditions for a young child to start masking her powers and create an obscurus .

The Ariana-Osbscura theory would also explain the motivations behind the film’s Grindlewald. Either he was curious about Obscura when he knew Ariana, and that’s part of what prompted his famous duel with Dumbledore. Or he saw what the Obscura could do after the fact and that’s what sent him to America searching for an Obscura of his own.

Amightyslytherin goes on to use this theory to support another. “This ties in with the Dumbledore’s horcrux theory. This would mean that Dumbledore was partially responsible for his sister’s death, and thus did (or believe’s he did) cause the death of a person, splitting his soul to make the horcrux.”

While making an accidental Horcrux is exceptionally rare, we know that it is not impossible. Voldemort would eventually do so in his attempted murder of Harry Potter. By that time, the Dark Lord had his soul ripped into six pieces. Thus making it easier for a piece to fly off. But Dumbledore, grieving. He lost his best friend and possible lover. And his participation in the death of his sister might have made his soul vulnerable enough to split. 

That’s my personal theory, but there are so many more to discover. Go see Fantastic Beasts, then tell us what you think of amightyslytherin’s theory. I, for one, applaud it. 

Fantastic Beasts is out now in theatres everywhere.
