In the Harry Potter series, the death of Sirius was linked to an information scam directed by Voldemort. When Voldemort discovered that his mind could be connected to Harry Potter, he faked the image of Sirius being tortured by him in the Department of Mysteries of the Ministry of Magic and sent it to Harry Potter through a telepathic link. On his way to urgently contact Sirius, Harry Potter, under the misdirection of Kreacher, the house-elf, thought that Sirius had been captured by Voldemort, so he joined Hermione, Neville, Luna, and Ron to save Sirius. When they arrived, they found out that it was a hoax. Sirius had not been caught by Voldemort at all; it was Voldemort's Death Eaters who were waiting for them. A group of teenagers began to evade and resist the pursuit of the Death Eaters, and Sirius, Lupin, Moody, and other members of the Order rushed to the Ministry of Magic to rescue them when they heard from Snape. Sirius was killed by his cousin, Bellatrix Lestrange, in the middle of a fierce battle between the Order and the Death Eaters. However, in the book, Sirius is fighting Bellatrix on the dais, and he dodged the first of Bella's attacks. The book does not say what spell Bella cast on him the second time, but it says that the spell hit him right in the chest, and his eyes went wide with horror. Then he fell through the veil of the archway and disappeared with a look of fear and surprise, never coming out from the other side. When the movie dealt with this part, it directly said that Bella used a death curse on him (Avada Kedavra, the curse was green, but the book described the first curse Bella used on him as red, and the second curse did not mention color) and hit him, so he died. So there was also the possibility that Sirius had fallen into the Veil and died. Harry Potter and the Order of the Phoenix is not enough. Please click to read the novel!
In the original novel, Sirius died at the hands of his cousin Bellatrix Lestrange while trying to save Harry Potter and his friends. Voldemort faked the image of Sirius being tortured by himself in the Department of Mysteries of the Ministry of Magic and sent it to Harry Potter through a psychic link. Under the misdirection of Kreacher, Harry Potter thought that Sirius had been captured by Voldemort, so he joined Hermione, Neville, Luna, Ron and other small partners to save Sirius. When they arrived, they found out that it was a scam. Sirius had not been caught by Voldemort at all; it was Voldemort's Death Eaters who were waiting for them. A group of teenagers began to evade and resist the pursuit of the Death Eaters, and Sirius, Lupin, Moody, and other members of the Order rushed to the Ministry of Magic to rescue them when they heard from Snape. Sirius and Bellatrix fought on the dais as the Order of the Phoenix fought the Death Eaters. Sirius dodged Bella's first attack and laughed at her. The second time, the book did not specify what spell Bella used. It only described that "the spell hit his chest..." His eyes went round with horror, and then Sirius fell back into the veil of the archway, disappearing with a look of horror and surprise, never to come out from the other side. Harry tried to climb onto the platform to check, but Lupin held him tight and told him Sirius was dead. In the movie, it was directly stated that Bella used a death curse on Sirius (Avada Kedavra, green) and hit him. However, the first curse Bella used in the book was red, so it was not a death curse. The second curse did not mention the color. It was not clear whether Sirius was killed by the curse or fell into the veil and could not return. Harry Potter and the Order of the Phoenix is not enough. Please click to read the novel!
In the original novel, Sirius fell into the archway (the Hall of Death) after being hit by a common offensive spell. Harry and Luna could hear voices behind the curtains, but Hermione and Ron could not, and they assumed that beyond the arch was the Underworld, which separated the two worlds. When Sirius fell into the archway, Lupin caught Harry, who was desperately trying to get inside to find Sirius, and told him that Sirius was dead and that there was no way out of the door. Sirius's fall to the other side of the veil is described with great restraint, but it is a difficult scene to accept. Harry Potter and the Order of the Phoenix is not enough.

In some fanfiction, Sirius Black might be wrongly portrayed as a Death Eater for the sake of creating an alternative or dark storyline. But in the original 'Harry Potter' series, he is not a Death Eater at all. He was framed by Peter Pettigrew.
In the Harry Potter series, Sirius fell into the curtain and died, but the book did not specify what the curtain was. It was only known that the room was like a circular theater, extending from top to bottom until a stone platform appeared at the bottom. Living people could never return after entering. Harry Potter and the Goblet of Fire was not enough. Everyone, please click to read the novel!
There could be a fanfiction that delves into the magical afterlife concept in relation to Sirius Black's death. It could be about his spirit lingering in a limbo state, trying to communicate with the living. This would add a new dimension to the story, as it might involve some new magical elements and how the wizarding world deals with spirits and the afterlife.
One possible scenario in such a fanfiction could be that Sirius is somehow forced or tricked into becoming a Death Eater. Hermione might then try to rescue him from the dark side. Maybe she discovers some ancient magic that can reverse the dark mark's influence on him.
One interesting Sirius Black as a Death Eater fanfiction could be 'The Darkened Path of Sirius'. In this story, Sirius might be forced into the Death Eater ranks due to some dark family secrets. Another could be 'Sirius's Fall and Redemption'. It might explore how being a Death Eater changes him and his journey back to the good side. And 'The Alternative Sirius' could show a world where Sirius is a Death Eater from the start, changing the whole dynamic of the Harry Potter universe.
In many fanfictions, Harry becomes more withdrawn after Sirius' death. He might lose his trust in the adults around him more easily, feeling that they couldn't protect Sirius, so he tries to be more self - reliant. He also could become more brooding and angry, his emotions more volatile as he grapples with the sudden and tragic loss.
Some fanfiction writers might make Sirius Black a Death Eater to explore the idea of redemption in a different way. If he starts as a Death Eater, then his journey to the side of good could be a more complex and interesting story. Also, it could be a way to add more mystery to the 'Harry Potter' universe by changing the nature of a familiar character.
Another idea is that Sirius, as a Death Eater, has some information that Hermione needs to defeat Voldemort. She has to convince him to give it to her while also dealing with his newfound allegiance. It could be a race against time as other Death Eaters suspect Sirius of being unfaithful to their cause, and Hermione has to protect him while also getting the crucial information.
