10 Harry Potter Fan Theories Confirmed By JK Rowling
5. Azkaban Was A Prison For Dementors
Can you imagine if Dementors were just free to roam around the country, just slipping up behind you, sucking out your soul and heading on to the next poor person out for a nighttime stroll? Solid pass, thanks a bunch. So the fan theory that was an early one to be confirmed, that Azkaban is as much a prison for them as it is for criminals, was an easy one to get behind!
Azkaban is a bloody grim place with a name steeped in history. Rowling wrote on Pottermore that Alcatraz and Abaddon birthed the prison and that it was allowed to exist as a means of keeping the Dementor population in check.
The darkest parts of the Wizard community were the prison's strongest supporters as it suited their goals. They were shot of the Dementors and they had a place to stick their criminals. In a way, it makes perfect sense. The prison was located on an island way out to sea, so there wasn't any chance of Muggles stumbling across it.
There wasn't much of a risk of escape either with thousands of Dementors floating about. What this confirmation really means is that there was a Hell in the world of Harry Potter, it was well known to Wizard-kind and for hundreds of years it was a beacon of success for various governments.
That one is pretty dark, all things considered.
