In the heart of the vampire city, the cloak of night draped itself over the cobblestone streets and towering spires, casting everything in an inky veil. Though the absence of natural sunlight made it difficult to discern between day and night, there was a palpable shift in the atmosphere that signaled the transition.
As dusk descended, the normally quiet alleys and bustling marketplaces began to stir with renewed vigor. Vampire denizens emerged from the shadows, their movements fluid and purposeful as they went about their nocturnal activities. The air crackled with a sense of anticipation, a collective energy that pulsed through the city like a heartbeat.
