DIASPORA OF THE DEMIURGE

EXTRAS

THE SYSTEM

TAU CETI, LIVE

The system turning at its real period ratios. Scrub through four centuries in Earth dates or the colony's own calendar. Click anything for its record.

SYSTEM CHART

A single plate. Two inhabited neighbourhoods, six astronomical units apart, and the scale break that is the only honest way to draw them together.

THE FLEET

EIGHT HUNDRED YEARS

The full dispersal, with what became of them. Distance compressed by the square root so the near and the far stay visible at once.

DICTIONARY OF DEMIURGES

Every mind named in the books, with the real tradition and figure each draws from.

THE COLONY

THE ITHACAN CALENDAR

Nine months, 194 sols of thirty hours. Founding Day falls on the third of Sextus. Convert any date, either direction.

COLONY GENEALOGY

Fifty-four colonists raised from the Codex, the households they formed, and the generations that followed.

THE ECOSPHERE REGISTER

Everything Athena brought, when, and under what constraint — searchable. Including what Ithaca will never have, and why.

COLONY SITE SURVEY

Athena's own site plans for Plateau Sector 04, at full size and in colour.

THE ARITHMETIC

THE WORKING

Why the approach was bent fifteen degrees. How you weigh a world you are flying straight at. What it costs to move water without breaking it. The derivations behind every figure the book marks with a dagger.

Nothing in the novels depends on reading this. It is here because the numbers are real and someone will want to check them.
