Senera Map Scale and Travel Planning

This article records out-of-world cartographic conventions and travel estimates used when planning Senera. The grid references, pixel measurements, and route calculations are editorial tools, not in-world terminology or surveyed canonical distances.

Controlling Scale

The current Map of Senera is provisionally treated as a scale map. The controlling ruler is the Gulf of Inespell, which extends approximately 125 miles inland and is approximately 63 miles wide at its mouth. Measuring the gulf on the map gives a working scale of approximately 0.135 mile per pixel, or approximately 7.4 pixels per mile.

The resulting working calibration is:

Map canvas: 4,500 by 4,500 pixels
Full map width: approximately 608 miles
Main planning-grid cell: 300 pixels, or approximately 40.5 miles per side
Main-cell diagonal: approximately 57 miles
Main-cell area: approximately 1,640 square miles
Three-by-three subcell: 100 pixels, or approximately 13.5 miles per side
Subcell diagonal: approximately 19 miles

Conflicting dimensions in older regional descriptions should be reconsidered against this ruler rather than used as independent calibrations. The convention can be revised if the map itself is later redesigned.

Nested Planning Grid

The planning map uses main cells labelled with an uppercase letter and a number. Each main cell can be divided into a three-by-three lowercase grid. Parentheses distinguish a nested subcell from a main cell: B4(c3) means subcell c3 within main cell B4, not main-grid C3.

A range uses the same convention. B3(b1-c2) denotes the rectangular group comprising b1, c1, b2, and c2 within main cell B3.

Current Western Senera Placements

Maiden’s Field occupies B3(b1-c2), approximately 27 miles east to west and 27 miles north to south, or about 729 square miles.
Maiden’s Port lies on the coast east of B3(c1).
Maylert lies within B4(c3). Use the subcell centre only as a provisional measuring point until its exact location and road alignment are drawn.
Rannekford is provisionally measured from the settlement dot at approximately (1185, 2135) on the source map.
Port Mibram is provisionally measured at approximately (1250, 2010).

The Rannekford and Port Mibram points are approximately 19 miles apart in a straight line, before allowing for the road’s actual course.

The uncertain handwritten reading previously discussed as “Wylfen Fields” should not be equated with Maiden’s Field. The D4-E5 region appears to be the Western Foothills.

Route Decisions

Andrew and Sapphire take the eastern road from Rannekford through Port Mibram toward Maiden’s Field. Their loaded brewery carriage and settlement-by-settlement investigation make travel days and elapsed mission days different quantities.
Hellion and his group take the western road. Maylert is a possible stopping place on that approach. Its placement bends a route through Maylert southward, so estimates that treated the western road as a direct Rannekford-to-Field line do not apply if Maylert is a required waypoint.

Travel Assumptions

Use these as sustainable daily rates rather than brief maximum speeds:

Loaded merchant or brewery carriage: approximately 15–20 effective road miles per travel day
Light passenger carriage or mounted group: approximately 18–24 effective road miles per travel day
General slow, normal, and fast overland planning bands: approximately 18, 24, and 30 miles per day
Sustained high-speed travel requires organized relay horses; one team cannot maintain relay speeds

Raised embankments and well-maintained commercial roads can support the upper part of a band. Mud, flooding, a failed weir, a washed-out bridge, a closed ferry, military activity, or investigative stops can add detours or whole non-travel days.

Provisional Route Estimates

These ranges combine straight-line geometry with allowances for plausible road curvature and delta crossings. Exact road polylines have not yet been drawn.

Eastern Road Through Port Mibram

Rannekford to Port Mibram: approximately 22–27 road miles
Rannekford through Port Mibram to the nearest part of Maiden’s Field: approximately 45–55 road miles, or roughly 2–4 loaded-carriage travel days
To a representative interior destination: approximately 65–80 road miles, or roughly 3–6 loaded-carriage travel days
A farther western or northwestern destination may be approximately 85–100 road miles away, or roughly 4–7 loaded-carriage travel days

Investigation and assistance in settlements should be counted separately from those travel days.

Western Road and Maylert

Using the centre of B4(c3) only as a provisional point:

Rannekford to Maylert: approximately 39–48 road miles
Maylert to the nearest part of Maiden’s Field: approximately 54–66 road miles
Maylert to a representative interior destination: approximately 70–86 road miles
Rannekford via Maylert to the nearest part of the Field: approximately 94–114 road miles, or roughly 4–7 days for a light carriage or mounted group
Rannekford via Maylert to a representative interior destination: approximately 110–134 road miles, or roughly 5–8 days for a light carriage or mounted group

These totals supersede the earlier short western-route estimate if Maylert is on the travelled route. If Maylert is only an optional detour, the direct western road requires its own traced alignment before receiving a durable mileage.

Open Cartographic Decisions

Trace both roads and their principal bridges, ferries, causeways, and relief stations.
Place the Maidenfeld keep and define which destination inside Maiden’s Field ordinary speech means.
Decide whether Maylert is a mandatory western-road waypoint or an optional rest detour.
Reconcile older regional dimensions against the Gulf-controlled ruler.
Consider adding a scale bar to the Bastion Falls site’s Map components.
Audit existing narrative phrases such as “several days away” against the geography rather than using them to calibrate it.
