In the year 1438, amidst the howl of winter winds, a cloaked figure scurried across the snow-clad cobbles of Prague. The town square was deserted save for him and the shadow of his chronometric device, hidden under drapes of silence. He sought the one known as the keeper of the Blood Clock, rumoured to stretch time into a bittersweet eternity.
As he knocked thrice at an ancient oak door, it creaked open to reveal a world ravaged by ages yet untouched. Inside, a library bloomed with books that whispered in dark prose, calling forth memories of past futures.
Bertram of London, wandering the fogs of 1887, stumbled upon an epoch riddle: "Today is to be the unseen tomorrow". An enigmatic phrase etched on stone, half-buried in the cryptic tunnels beneath the Thames, guiding his feet through shadows and light.
Haunted by the phrase, he penned letters to himself, trapped in a cyclical loop, discovering in each new dawn a reflection of nightmarish grandeur.
