The stories span several eras, from the time of the Romans to modern times. They are intrinsically linked to the forest and to the mining activity that has structured the region over the centuries. Since La Borne de Fer does not have any legend, the artists themselves invented legends from the history of iron mining and a character who had haunted the woods since antiquity.
In the writing of the stories, the theme of borders is very present. It is approached at different levels: the first, most obvious, is that which concerns the border between the space of the forest and more civilised spaces (town, fields, farms, etc.). Another has been established between the human and the monster, or rather the way we view the monster. We can also envisage a boundary between the time of the walk and the spaces of time summoned by the stories.
Other themes are reflected in the texts, in particular that of the lure of profit. The traces of iron mining in the landscape, visible everywhere in the forest, are a reminder of how many people throughout history have sought to enrich themselves in this territory. The trail chooses to transpose this quest for wealth by creating a legend in which the men are not only looking for ore, but a real treasure hidden in the heart of La Borne de Fer.
The musical composition is part of an already very rich sound landscape.
At the beginning of the journey, the voice of a narrator appears on a large path separating forest and field. The male voice is that of the person who created the app that the listener is using to find a lost treasure. We also hear a female voice trying to lure the listener into the forest, as she has been trapped there since ancient times.
The contrast between these two voices creates a clear boundary between the wilderness (the woman trying to lure the listener into the forest) and the civilised world (the game master who created the app). Throughout the trail, we hear a voice that oscillates between the spoken and the sung, in order to recall the world of tales, which have been accompanied by instruments since the dawn of time. Antoine Spindler plays pizzicato (plucked strings) on his viola to recall this aspect.
