Yrro
A figure of the S’pht creation myth — one of two beings (with Pthia) who fled the W’rkncacnter, settled Lh’owon, and brought the S’pht as servants; remembered as master, destroyer, and grief-stricken liberator of his people.
What the source establishes — canon
The creation myth — flight and settlement. A S’pht terminal (rendered via translator) describes the primordial situation: “In primordial space, timeless creatures made waves. These waves created us and the others. Waves were the battles, and the battles were waves. Fleeing all W’rkncacnter, Yrro and Pthia settled upon Lh’owon. They brought the S’pht, servants who began to shape the deserts of Lh’owon into marsh and sea, rivers and forests. They made sisters for Lh’owon to protect and maintain the paradise.”1
Yrro and Pthia are thus the beings under whose direction the S’pht terraformed Lh’owon and created its moon-sisters.
Pthia’s death and Yrro’s act of imprisonment. The myth continues: “When the W’rkncacnter came, Pthia was killed, and Yrro in anger, flung the W’rkncacnter into the sun. The sun burned them, but they swam on its surface.”1
The W’rkncacnter were not destroyed — they were imprisoned in Lh’owon’s sun, still alive, swimming its surface. This imprisonment is the result of Yrro’s rage following Pthia’s death.
Yrro’s abdication. After flinging the W’rkncacnter into the sun, Yrro “became an angry master, bleeding for his failure, grieving for the loss of Pthia. He broke the S’pht into eleven clans, and spread them over Lh’owon.”1 His direct speech is recorded:
“I Yrro, who was your master, have failed to preserve you. Take your royalty to guide you, and live upon the paradise that you built for me.”1
The ancient station. A separate terminal identifies an ancient station on Lh’owon as Yrro’s instrument of imprisonment: “you must activate the ancient station that Yrro used eons ago to trap the W’rkncacnter.”2 This station is later referred to directly as “the Yrro station” — Tfear deploys the trih xeem and moves his flagship to board it.3
The W’rkncacnter’s prison described independently. S’bhuth’s knowledge is framed as legendary only: he “knows only legends about the W’rkncacnter, imprisoned in Lh’owon’s sun.”2 This confirms that Yrro’s act of imprisonment passed into myth across multiple cultures, but its mechanism was not fully understood even by those closest to the site.
Yrro described as “all powerful.” In a S’pht historical account (via translator) describing the clan wars and the exile of the S’pht’Kr to K’lia, Yrro is referred to as “the all powerful Yrro” — it is he who “sent K’lia out to the stars,” carrying the S’pht’Kr clan into deep space.4
The “yrro(farcast)” gloss. A heavily corrupted Pfhor terminal uses the compound “yrro(farcast)” to describe pattern chips required to activate a power grid.5 The parenthetical reads as a translator gloss: the Pfhor term “farcast” glossed against the proper noun “yrro.” This may indicate Pfhor naming of the technology after Yrro, or a translator artifact; the terminal is too corrupted to establish further context.
S’pht reflection on their own origins. A S’pht clan-lord’s account raises the question of whether the myths were literally true: “perhaps the myths were true, and we were actual servants of Yrro and Pthia. Perhaps they built us, or we were part of a larger group who came to Lh’owon.”6 This is a S’pht’s own uncertainty, not a confirmed fact — the source presents it as debate, not conclusion.
W’rkncacnter cosmology (context). A terminal describes the W’rkncacnter independently: “those things that live in chaos, creating it around them. At the beginning of the universe, they were unmistakable in their entities, but as time has gone by, their existence has become difficult to detect among the chaotic elements of the universe, hidden in stars, trapped in storms, forever looking along the event horizons of black holes.”2 Their mythos is said to have “survived throughout the galaxy for over sixty million years.”2 This is the broader context within which Yrro’s act of imprisonment sits.

Source-silent / open questions
- What Yrro is. The pack does not identify Yrro’s species or nature beyond the myth — the S’pht themselves are uncertain whether Yrro and Pthia built them, or whether they were part of “a larger group” that came to Lh’owon.6 Any connection to the Jjaro or other precursor entities is not stated in these volumes.
- Pthia’s identity and nature. The pack establishes that Pthia died when the W’rkncacnter came, and that Yrro’s grief drove the imprisonment act — but Pthia’s nature, species, and relationship to Yrro are source-silent.
- Mechanism of imprisonment. The myth says Yrro “flung” the W’rkncacnter into the sun.1 The station is separately described as the instrument Yrro used to trap them.2 How these two accounts relate — whether the station is how the flinging was accomplished — is not resolved in the pack.
- How many W’rkncacnter. The pack uses plural throughout. Whether the sun of Lh’owon holds one or many is source-silent.
- Yrro’s fate after the abdication. The myth ends with the speech to the S’pht clans. What happened to Yrro afterward — whether he departed, died, or transformed — is source-silent.
- “Yrro(farcast)” in Vol 1. The terminal is severely corrupted. Whether this represents Pfhor naming of Yrro’s technology, a translator artifact, or something else cannot be determined from the available text.
- Vol 7 (Curiouser and Curiouser). The Durandal terminal in the pack contains no direct Yrro reference; it provides garrison flooding context only. It is included in the pack but contributes no Yrro-specific content.
