The theme of mystery also runs through a lot of Butcher and Blackbird fanfic. Their backstories are often not fully explored in the original, so fanfic authors like to create their own mysteries around who they are, where they came from, and what their true motives are. This adds an extra layer of intrigue to the stories.
There's also 'The Butcher's Secret' fanfic. It explores a side of the Butcher that we don't often see in the original material. The author does a wonderful job of building on the existing lore and creating a new and engaging story line. The relationship between the Butcher and Blackbird is really well - portrayed in this one.
The blackbird could also be a messenger. In some magical lore, birds carry messages between different realms or people. So in the context of a Harry Potter fanfic, it could be bringing an important message to a character, perhaps a warning about an upcoming danger or a clue to solve a mystery.
It's not straightforward to determine. 'Blackbird' might have some roots in real experiences, but it could also be a completely made-up tale with no direct connection to actual events.
In most cases, 'Blackbird' is not a true story. It could be a work of imagination, drawing from common themes and tropes to craft a compelling narrative.
One way is to have it as a guide. For instance, a young wizard or witch could be lost in a forest near Hogwarts, and a blackbird flying overhead could lead them to safety, like to a hidden passage or an old, forgotten hut that holds some important magical item.
I'm not sure of a specific 'Blackbird Fly' Sherlock fanfic with a unique plot off the top of my head. But a unique plot could involve the blackbird being a time - traveling device in Sherlock's world. It takes him to different eras where he has to solve mysteries that are somehow related to the present - day cases he's working on.
One funny story is that the SR 71 was so fast that it could outrun its own fuel. When it was flying at extremely high speeds, the fuel consumption was massive. But it was so speedy that it could cover long distances before the lack of fuel became a critical issue. Pilots had to be really precise in their flight planning because of this unique situation.
Well, obviously the Butcher Gang themselves are the main characters. They consist of Charley, Barley, and Edgar. Each of them has their own distinct personalities. Charley might be the more impulsive one, Barley could be a bit more cautious, and Edgar might be the most unpredictable.
