A Grammar of Light

How the Ithra wrote, and how we learned to read them

The Ithra did not invent writing. They inherited it from the sea, as a way of flashing in the dark, and spent three million turns making it beautiful.

Pulses

The oldest layer of the language is not visual at all. It is temporal: a sequence of pulses and rests, long and short, like a heartbeat with opinions. The Pulse Stone of the Shallows preserves some of it as scratches. Almost every later form of Ithran writing is a way of freezing those pulses into a shape that can be read all at once.

The aperture

By the Age of Lanterns the Ithra had settled on the form the Institute calls the aperture. Every glyph is drawn inside a circle — the rim — with eight spokes and three radii: the core, the middle ring and the rim itself. A glyph is a handful of strokes on that lattice: an arc on the middle ring, a ray along a spoke, a chord across the rim, a single luminous dot.

A vowel. Vowels close the rim and light the core — they are the open, sounding letters.

A consonant. Consonants break the rim with a gap, and the gap’s position is part of the letter.

The rim is the key to reading it. An unbroken rim is a vowel: a sound that is allowed to ring. A broken rim is a consonant: a sound that stops. The Ithra thought of speech as light that is either allowed out or held in, and their alphabet says so.

Words

Letters are strung along a thread of light to make words, the way lanterns were strung along the sea wall of the Senn Reach. Names, and anything sacred, are written instead as a rosette: the letters arranged around a circle, each facing outward, like a crowd around a fire.

“Ithra”, in rosette form — their own name, which means those who keep the light.

We did not know any of this for forty-one years. What broke it open was the Accord of Dusk. The treaty that ended the Quiet Schism was inscribed twice, once by each faction, and the two factions wrote in slightly different styles. Two texts with the same meaning, in two hands: it was a Rosetta Stone the Ithra had built for their own reasons, and it was enough.

We read the Accord, and then we could read everything, and then we wished for a while that we could not.

Try it

The Institute’s transliteration maps our alphabet onto theirs, letter by letter, so any name can be written in the aperture script. It is not how an Ithra would have written your name. It is how their alphabet would have held it.

The full synthesiser — with rosettes, stroke weights and export — is among the Instruments. Whatever you write there, the observatory remembers as your sigil.
