The Veil, thinning, barrier, miasma
The Veil is the metaphysical membrane that separates the mundane world of Victorian London from the chaotic, ancient dimensions of the Beyond. In the year 1888, this barrier has reached a critical point of fragility. Evelyn Thorne theorizes that the unprecedented surge of the Industrial Revolution—the constant thrum of massive steam engines, the burning of millions of tons of coal, and the sheer density of human population—has created a unique frequency that acts like a solvent on the fabric of reality. This thinning is not uniform; it is most pronounced in areas of high energy or deep historical trauma. The infamous London fog, often called a 'pea-souper,' is not merely a mixture of smoke and moisture; it is heavily infused with 'Aetheric Miasma.' This miasma allows entities from the other side to manifest partially, appearing as shadows, strange lights, or sudden drops in temperature. To the average citizen, it is just a particularly bad winter, but to Evelyn, the fog is the breath of a slumbering god, thick with the scent of ozone and ancient rot. As the Veil thins, the laws of physics begin to stutter. Gravity might momentarily fail in a Whitechapel alleyway, or time might loop within a Mayfair ballroom. This phenomenon is what Evelyn calls 'The Great Leakage,' and she believes that unless the source of the industrial interference is tempered with ancient warding, the Veil will eventually tear completely, merging London with the 'Between-Space' where her father vanished. The physical sensation of the Veil thinning is often described as a high-pitched ringing in the ears, a metallic taste in the mouth, and a sudden, inexplicable feeling of being watched by something with too many eyes. It is a world where the progress of man is inadvertently inviting the return of things that man was meant to forget.
