The Bedrock

"What holds the city up also holds it down."

Below the Fold, the city becomes something different. BVHI's deep infrastructure defines the physical reality of the Bedrock, tunnel networks, maintenance corridors, power routing systems, and the deep-transit arteries connecting the Spire to the rest of the world. But BVHI does not have exclusive occupancy of the city's underspace. The Halfling Depth Access and several unofficial transit routes ensure that the Bedrock contains intersecting interests.

The Bedrock is not a residential or commercial zone in the conventional sense, but it is inhabited, by BVHI operational personnel, by the people who navigate unofficial transit routes for reasons they prefer to keep unofficial, and by things that exist in the harmonic irregularities of the deep infrastructure that the BVHI maintenance logs file under "Legacy Anomalies" and send to Signal Crown, where they are also not resolved.

The Deep Transit Network

BVHI's operational pride, the tunnel system beneath the Spire that connects to continental infrastructure, services every major surface building's power and data routing, and contains within it the sub-city transit freight lines that move materials too large or too sensitive for surface transport.

Access to the Network proper requires BVHI credentials or a Transit Bond. The maintenance corridors require more. In practice, multiple parties move through the Network without proper authorization regularly, the tunnels are extensive, BVHI's monitoring is not uniformly active in legacy sections, and the Halfling junction the Quiet Blocks provide gives one faction near-direct access.

Notable locations: - Junction Fourteen: The deepest publicly accessible BVHI transit station, two levels below Accord Station. Clean, well-lit, surveilled, and the last point at which civilian personnel are expected. Below Junction Fourteen, the environment is operational. - The Fault Corridor: A legacy maintenance route running beneath the Resonance Common that BVHI's own documentation flags as "structurally stable, harmonically irregular." The irregularity is a function of the Anchor Stone above. BVHI does not work in the Fault Corridor without Seismic Engineering supervision. Work orders for the corridor are frequently requested and rarely completed. - The Unnamed Junction: The Halfling access point. Does not appear in BVHI's public or internal documentation. Does appear in the Shadow-Census cross-reference index under a file designation that translates roughly as "mutually acknowledged deniability."

The Deep Vault

Below the transit network, the Spire contains a BVHI Deep Vault cluster, the physical and digital asset storage that forms the backbone of the city's financial security architecture. Physical safety deposit infrastructure, harmonic-sealed document preservation, and the deep cold storage units where long-duration assets requiring both physical and magical stabilization are maintained.

The Vaults are the most secure non-arcology location in the city. Vault-Security Auditors run penetration testing continuously. Every material and system used in construction is BVHI-spec. The only way in or out is through access points that require active BVHI verification by a credentialed Clancorp member in person.

The Vaults contain, among other assets, the physical originals of every Accord registered in the Spire's history. The LGT is aware of this. The reason the LGT does not have copies stored elsewhere is documented in a contract between the Trust and BVHI that neither party has released publicly. The terms are understood by both to be mutually disadvantageous to disclose.
