Blackstone House had an uneasy reputation before its current owner disappeared. The owner was a muggle, but the house was built by wizards, so rising young Auror Harry Potter is sent to investigate. But someone else is looking into Blackstone House, and Harry finds himself in an uneasy alliance with magical vigilante John Constantine.

John helps the protagonists in the mystery of Sirius Black. Will Black be set free at the end of this by the Ministry or will it have the canon ending? You'll just have to read to find out. sequel 2 Hellblazer and the Chamber of Secrets. Don't own any of the dc and Potterverse characters. I'm sorry 2 say that this story is discontinued. LeonDesdichard has adopted the series on AO3.

John goes more into his exorcist job while helping Harry with this story's mystery. This story introduces the Halliwell sisters from the original charmed show. They'll be more like OCs because I don't want to risk ruining their personalities, and this is about before they were adults. This is a sequel to Hellblazer and the Philosopher's Stone. I own nothing.

An 11 yr old John Constantine joins the adventures of Harry Potter. all translations for other languages will be at the bottom of each chapter they're in. unfortunately, I don't own either the characters from the Constantine tv show or the Harry Potter characters.
