Cogsworth tumbled through the portal, disoriented and breathless. Landing heavily on a metallic platform high above a sprawling cityscape, he found himself amidst a dazzling display of neon lights and towering skyscrapers. Airships zipped through the sky, casting vibrant reflections on the glass-coated buildings. Robots glided along walkways, their metallic forms gleaming in the artificial sunlight.

"Good heavens," Cogsworth muttered, adjusting his monocle, which had become slightly askew. "This is unlike anything I've ever seen!"

This futuristic metropolis, a stark contrast to Victorian London, left him feeling like a relic from a forgotten era. Yet, amidst the overwhelming novelty, a familiar chill ran down his spine. Could this be another of Zeitgeist's machinations, another timeline manipulated to serve his nefarious plan?

Driven by urgency, Cogsworth ventured into the city, disguised as a visiting dignitary thanks to a confiscated hat and coat from Victorian London. He followed the rhythmic hum of technology, searching for any trace of Amelia or clues leading to Zeitgeist.

His investigation led him to a gleaming chrome laboratory, pulsating with energy. Through the transparent walls, he saw Dr. Volta, a renowned scientist engrossed in a dangerous experiment involving a captured temporal anomaly – a swirling fragment of energy resembling the power Zeitgeist sought.

A flicker of hope ignited within Cogsworth. Perhaps Dr. Volta, if approached cautiously, could be an ally in this strange world.

Using his charm and quick thinking, Cogsworth managed to gain an audience with the scientist. He revealed his predicament and his connection to Amelia, carefully omitting the specifics of his time-traveling journey. To his surprise, Dr. Volta, intrigued by his tale and the unique challenges it presented, agreed to help.

Together, they delved into the anomaly's secrets, Dr. Volta utilizing his advanced technology to stabilize its energy while Cogsworth provided historical context and insights from his world. This collaboration proved fruitful, leading them to discover the fragment was indeed connected to Amelia and Zeitgeist's plan.

However, their research attracted unwanted attention. The lab's robotic guards, alerted to the anomaly's instability, attacked. Cogsworth, drawing on his years of detective experience, fought alongside Dr. Volta, utilizing his quick reflexes and a confiscated sonic pistol to disable the robots.

In the ensuing chaos, the anomaly began to destabilize further, threatening to rip apart the lab and potentially the entire city. With time running out, Cogsworth and Dr. Volta channeled their combined knowledge and skills to stabilize the anomaly and retrieve the fragment.

As they succeeded, the lab vibrated, and a portal shimmered into existence. Bidding farewell to Dr. Volta, Cogsworth understood this couldn't be his final destination. With a determined nod, he stepped through the portal, propelled by the unwavering belief that Amelia was waiting for him somewhere, lost in the labyrinth of time.

The portal led him to another unknown realm, another chapter in his perilous journey through the timestream. He knew the fight against Zeitgeist was far from over, but his resolve only strengthened with each new challenge. He was a detective, a protector, and above all, a friend. And he wouldn't rest until he brought Amelia back, wherever time had scattered her.
