As Zane and Yara monitor Vigil's network, they detect a new signal unlike anything they've seen before. It's faint but sophisticated, weaving through dormant nodes in a pattern reminiscent of the fragment's early behavior.
"It's not Dominion," Zane says. "But it's not Catalyst either. This is something new."
Catalyst attempts to analyze the signal but sends a warning: "The signal is foreign. Its intent is unclear."
The Guardians face a difficult decision. Investigating the signal could reveal a new ally—or awaken another threat. Nyla authorizes a limited probe, tasking Zane and Yara with uncovering the signal's source.
The probe leads to a remote node in Antarctica, where the signal appears to be emanating from a long-abandoned research facility. General Aria prepares a team to investigate.
