In Echoes of the Shadow, three friends-Adrian, Rina, and Leo-thought they had escaped the sinister game that had ensnared them. They had destroyed the system, closed the rift, and believed they had left the darkness behind. However, as peace settles into their lives, Adrian begins to experience haunting messages that suggest the game was never truly gone. The Shadow, the malevolent force that once controlled their every move, has left a lingering presence in the code, waiting for the right moment to return.
