Prebuilt Tunnels

Artificial corridors below the Deprecated Zone that predate any known construction timeline for the city. Structurally sound, clearly artificial, not on any map, and not connected to the operational layer's known infrastructure.

The Kroty's Diggers encountered structurally sound versions during Year 2 excavation. Rodik mapped what he found privately and told no one outside the Troika. The Luipaarden's Spotters have documented that Lara Opus regularly uses tunnels that bypass their checkpoints through corridors that appear on no map. The Păianjenii noted once, in an internal memo that has never been sold: "We mapped the Underpass. She mapped something else."
