GS: CASE FILE - A WEB OF SHADOWS

Their first clue came in the form of a shadowy figure watching them from a distance. When Ayan approached, the figure vanished, leaving a single object: a pocket watch.

"This isn't just a city," Nitya realized, examining the watch. "It's a clockwork mechanism. Every part of it is connected, synchronized."

As they delved deeper, they discovered that the city's inhabitants were not people but projections, their movements dictated by the city's rhythm.

"We're inside the nexus," Haider said, his voice filled with awe. "This entire city is a construct, a manifestation of Seo's control."

Their mission took them to the heart of the city, a towering skyscraper that pulsed with a sinister energy. Inside, they encountered Seo's defenses: shifting hallways, illusions that played on their fears, and riddles designed to test their resolve.

The climax came when they reached the top of the skyscraper, where Seo awaited them.
