The Backlund Metro emerges in Volume 2 as a marvel of steam-powered engineering, its black metallic serpentine carriages threading beneath the city while channeling locomotive smoke through overhead pipes to street-level chimneys. Across the series, this underground railway transforms from a mere feat of industrial ingenuity into a vital artery of the city’s hidden world, facilitating clandestine movements and becoming entangled in the machinations of secret organizations and supernatural threats. Its evolution mirrors the broader shift from mechanical wonder to a nexus of intrigue, where the boundaries between technological progress and mystical danger blur.
