The Location Designation System

Overview

All locations in the known world follow a standardised hierarchical address format. The system distinguishes between major, fortified population centres, designated as Nodes, and the chaotic wastelands of Eidolon, designated as the Eidolon Demarcation Zone. The two formats reflect the two realities they map: structured society on one side of the walls, unmapped danger on the other.

The Node format

The Node format is used for all locations within a major settlement's walls. Each city is considered a major Node in the old Precursor network, a designation that predates Meridian's current administration and has never been formally retired. The format is hierarchical, moving from the broadest geographical unit to the most specific.

Standard Node format: Node: [City Name] / [District] / [Sector ID] / [Structure ID] / [Unit ID]

Districts

The largest geographical division within a Node. Meridian's five districts are:

• Nexus — Commercial and residential hub
• Zenith — Corporate spire
• Ergo Loom — Artisan and tech sector
• The Docks — Industrial
• Dún Brón — Historic old quarters

Sector ID

A prefix and number that divides each district into smaller functional zones. The prefix indicates the zone's primary function.

• HB-# — Habitation Block, for example HB-9 in Nexus
• CB-# — Commercial Block, for example a market sector in Nexus
• IB-# — Industrial Block, primarily in The Docks
• AB-# — Arcology Block, the massive spires in Zenith
• HS-# — Heritage Sector, the historical zones in Dún Brón

Structure ID

The specific name or designation of the building or complex within a sector. Naming conventions vary by district.

• Spires: Spire A, Spire B, Spire C
• Towers: Anima Tower, Plaza-Tower A
• Warehouses: Warehouse 12, Shed 4
• Evocative names: In districts like Ergo Loom, structure names tend to be more creative, for example The Artisan's Coil

Unit ID

The final and most specific address component, identifying the exact location within a structure.

• Vertical units in spires: The format is [Floor]-[Unit]. For example, Unit 7-34 is Floor 7, Unit 34.
• Other units: A simple unit number such as Unit 3B, or a bay number such as Bay 3

The Eidolon Demarcation Zone format

The E.D.Z. format is used for all locations outside major Nodes, in the wastelands of Eidolon. It is deliberately less precise than the Node format, reflecting the unmapped and dangerous nature of the territory. Navigation in the E.D.Z. relies on informal regional names, cartographical grid references, and site designations that have accumulated through use rather than through official record.

Standard E.D.Z. format: E.D.Z. / [Region] / [Grid Coordinate] / [Site Designation] / [Local Address (if applicable)]

Regions

Broad, informally named geographical areas within the wastes. Current working designations:

• The Salt Flats
• The Glass Forest
• The Sunken Coast

All three are working names, subject to formal designation as exploration expands.

Grid coordinate

A standard cartographical grid reference used by Echo Divers and scavengers for navigation, for example 7G-3E. Grid coordinates are the primary navigation tool in the E.D.Z. in the absence of reliable landmarks.

Site designation

The common name or designation for a specific ruin, outpost, or landmark within a grid area.

• Precursor ruins: Ruin-Alpha, The Whispering Tower
• Settlements: Lookout Point, Scrap-Town

All current site designations are working names.

Local address

An informal internal address used within an established E.D.Z. settlement, for example Hab-Block 3 / Unit 7.

Reference examples

The following confirmed addresses illustrate the system in practice.

Kaelen Corbin's apartment: Node: Meridian / Nexus / HB-9 / Spire C / 7-34

Sona's workshop: Node: Meridian / Ergo Loom / CB-4 / The Artisan's Coil / Unit 3B

Anima Dynamics server archive (decommissioned): Node: Meridian / Dún Brón / HS-2 / Storage Facility 7 / Sub-level 3

A Precursor ruin in the Salt Flats: E.D.Z. / The Salt Flats / 12A-88C / Ruin-Gamma

An apartment in a wasteland settlement: E.D.Z. / The Sunken Coast / 81F-12B / Scrap-Town / Hab-Block 3 / Unit 7
