The significance might be to give a new hope or mystery regarding Sirius. In the original story, Sirius's death was quite tragic. So in fanfic, 'the exit sirius veil' could be a symbol of a second chance, a way to bring him back into the story or at least explore his connection to the other side more deeply.
In Harry Potter fanfic, 'the exit sirius veil' could potentially refer to a concept related to Sirius Black and the veil in the Department of Mysteries. It might be a unique interpretation by the fanfic author where the veil has an 'exit' aspect, perhaps symbolizing a way to bring Sirius back or some connection to the afterlife that he is associated with.
I'm not sure specifically as there could be many different fanfics with that title. It might be about Sirius Black's exit or departure in some way within the context of the Harry Potter universe. Maybe it's about his escape from Azkaban, or his final moments in the story.
You could try searching on popular fanfic websites like Fanfiction.net or Archive of Our Own (AO3). These platforms have a large collection of Harry Potter fanfics and there's a good chance you'll find it there.
The 'lipstick Sirius veil' might represent a form of transformation or disguise in the fanfic. Sirius is a complex character, and perhaps the lipstick has the power to change his appearance when he passes through the veil. It could also be a metaphor for hiding something. The veil often has connotations of mystery and the unknown in the Potter universe, so the lipstick could be a key to understanding what lies beyond the veil in the context of the fanfic.
The significance of 'the ritual' in the Harry Potter fanfic might be related to the world - building aspect. It could be a key part of the fanfic's unique take on the wizarding world. Maybe it's a ritual that has been lost in time in the original series but is now resurfacing in the fanfic. This could attract the attention of different factions within the wizarding world, such as the Ministry of Magic, who might want to either control or suppress it. It could also be a symbol of a certain culture or group within the fanfic's world, representing their values and traditions.
The Lipstick Sirius Veil might be used to drive the conflict in the fanfic. Maybe different characters have different ideas about what the lipstick and the veil combination means. Some might want to use it for good, while others for evil. This creates a power struggle. For instance, if the veil is protecting a powerful magical object, and the lipstick is the key to accessing it, characters will fight over who gets to use the lipstick on the veil. Sirius could be caught in the middle of this struggle, having to choose a side.
In a Harry Potter fanfic, 'lightning on the waves' might have a spiritual significance. It could be a sign from the magical realm, like a message from the spirits of old wizards. For example, it might appear when a character is at a crossroads in their life, guiding them towards a certain path. It could also be a form of protection. If a place or a person is associated with 'lightning on the waves', it might mean that they are under the watchful eye of some powerful magical force that uses this as a way to keep them safe.
The significance of 'the green lady' in the fanfic could be that she represents a new force or character arc. For example, if she's a new teacher at Hogwarts, she might introduce a new type of magic that is related to the color green, like plant - based magic in a more advanced or unique way than what we've seen in the original series.
The significance of the 'room of desire' in Harry Potter fanfic can be that it adds a new layer of depth to the characters. It allows readers to see what the characters truly desire on a more personal level.
