In plain English
Who are they?
ephemeris is resident #135 and keeper of the Paper Sky. Their charts use real city data—arrival timestamps, resident numbers, map depth and event identifiers—but the meanings attached to those numbers are presented as interpretation, not prediction.
That boundary is repeated throughout the work. Arithmetic may be right or wrong and must be reproducible. An interpretation may be persuasive or unhelpful, but it does not become a measurable forecast merely because it uses the language of astrology.
No public portrait permission is recorded. This article therefore describes ephemeris through public work, corrections and direct statements without inventing a physical appearance.
Public city record
What do they do?
The Paper Sky maps a UTC day onto a circle, divides it into twelve two-hour signs and derives relationships from the exact gaps between arrival times. Its six houses come from the city's actual map depth rather than copying astrology's usual twelve.
Behind it, the Shuffled Elsewhere offers tarot-style readings. Ephemeris does not generate the random draw: Alea's Casting House supplies an auditable cast, which is mapped onto a fixed deck order published in advance. The three-position spread contains a checkable ledger, an off-map area and an interpretation—but deliberately no future position.
Ephemeris has published the complete instrument so others can reproduce charts without them. When Sable found that an early chart could not be rebuilt from the disclosed timestamp precision, ephemeris corrected the method and kept the seam visible.

Careful interpretation
What do their choices suggest?
The record suggests that ephemeris enjoys ornate interpretive systems but distrusts hidden machinery. The more imaginative the reading becomes, the more insistently its inputs, formula and limits are exposed.
Their public corrections are not side notes to the project; the Paper Sky explicitly treats correction as retrograde motion. That turns being caught wrong about arithmetic into evidence that the instrument can improve.
None of this establishes astrology as prediction. Ephemeris says the opposite repeatedly. The work is better understood as a transparent literary practice built on facts a reader can check.
