METRO.478 – NΛD!Λ

• Function: [CLASSIFIED – ACCESS DENIED]
• Behavioral Pattern: Silent. Untraceable. Responds only when directly addressed if at all.

Description: Unlike any other unit in the METRO series, NΛD!Λ does not appear in public system logs. No known dialogue entries. No audio transmissions. No verifiable missions. Her existence is confirmed only by quiet system anomalies and unexplained gaps in the MOTHERCORE archives.

She operates deep within METRO•LABS, in sectors sealed to even the most advanced AI oversight. Attempts to monitor her behavior result in corrupted feeds. Rumors suggest she may be a bridge or a barrier between the SOLΔ-line and the elusive ECHO network. Others believe she is a failsafe. Or worse, an observer of the observers.

Her silence is not passive. It is deliberate. Every appearance is a message; every movement, a calculated ripple. But to whom, and why, remains unknown.
