The dark tunnel could be a gateway to a different realm. The black hair tie on the wrist is the key to opening or closing it. A group of characters in a fanfiction are on a quest to find out the origin of the hair tie. When they reach the tunnel, they realize that one of them has to sacrifice the hair tie (and what it represents to them) to either save their world or gain access to a new world full of opportunities and secrets.
A character enters the dark tunnel while being chased. In a moment of panic, they use the black hair tie on their wrist to mark the path they've taken. As they move deeper into the tunnel, they discover that the hair tie has some sort of magical property that they were unaware of before. This property helps them face the challenges within the tunnel, like lighting up the way or warding off evil creatures.
The character could be in the dark tunnel, feeling lost. They look at the black hair tie on their wrist and remember a promise they made. This memory gives them the motivation to keep going and find a way out of the tunnel. For instance, if it was a promise to a friend who is in danger, the hair tie serves as a reminder of their duty.
One way is to have the character enter the dark tunnel while fiddling with the hair tie on their wrist out of nervousness. Maybe they find something in the tunnel that makes them realize the importance of the hair tie, like it was a key to unlock a hidden door.

Perhaps it symbolizes a form of restraint or hidden power. The black hair tie on the wrist is a physical object that can be used to hold things together, like hair.

The dark tunnel could be the place where this hidden aspect of the character will be revealed or challenged.
In fanfiction, a dark tunnel might symbolize mystery or a journey into the unknown. The hair tie on the wrist could be a simple accessory with a deeper meaning.

It could be a clue. Let's say a character goes missing in the fanfic, and all that's left behind is a hair tie on the wrist. The other characters then have to figure out who the hair tie belongs to and what it might mean in relation to the disappearance. This could lead them on a journey of discovery through the town and its secrets.

Perhaps the black hair tie is a reminder of a past love. Felicity is constantly haunted by the memories associated with it. She meets someone new in the fanfiction, and the presence of the hair tie creates a conflict as she tries to move on from her past while still holding onto this memento.
Perhaps in the fanfiction, the black hair tie on Jade's wrist is a clue to her past. She has amnesia and the hair tie is the only thing she has from her previous life.

A black hair tie on the wrist can be a link between different storylines or characters.

It could also be a symbol of a character's loyalty. If a character is part of a group, wearing the black hair tie on the wrist shows their allegiance to that group, and any threat to the hair tie can be a threat to the character's loyalty and relationships within the group.
