Sixth Course

A reef-city is not quiet. Every load-bearing course of the Long Shelf carries the percussion of everyone standing on it, and Sixth Course has spent a working life telling which strikes are speech, which are the city settling, and which are the sea.

Sixth Course is a sapient of Meridian, of the reef-city the record renders as the Long Shelf, and one of the analysts who serve its council. The name is the relay station's translation instrumentation's rendering of a percussion address, a pattern others strike to call Sixth Course, given by the instrumentation as a course of the city's lattice. What the count counts from, and whether the address names where Sixth Course was raised, where Sixth Course works, or something the record has no word for, the Archive has not asked.

Known History

• Served the Long Shelf council as an analyst before 2828 UCSD; when the service began, the record does not hold.
• Was among the Long Shelf's own analysts who, in 2828 UCSD, ran the comparison between the Sentinel's structured pulse and Meridian claw-percussion, after the council's petition to be consulted was authorised by Administrator-Voice Sohrel on the council's own terms (What Meridian Asked). The comparison found points of resemblance in phrasing and rhythm. It established no authorship, no origin and no connection, and Sixth Course's report to the council said so in those words.
• Received, through the standing Survey Corps data-exchange arrangement, Principal Tissadelle Shepherd's documented audio-routing method, a technique and not a conclusion. The council's acknowledgment, that the method costs nothing to receive and states nothing it did not already suspect, is recorded as the council's; who drafted it the record does not say.

Character Notes

Sixth Course's craft is older than the Sentinel question and would go on without it. The Long Shelf is built in secreted mineral composite, course on course, each generation adding to a lattice the one before it laid, and a city built that way is also an instrument: percussion on shell and structure travels through it at range, so a strike on an outwork is heard across the city, and the chemical channel drifts in slowly behind it to say what the strike meant. The council's analysts listen to the whole of that. The work is telling apart what the city is saying from what the city is doing, since a lattice under load has a sound of its own, and Sixth Course's reputation on the council rests on being slow to call either one the other.

That is why Sixth Course was given the Sentinel. The pulse, rendered into Meridian's own medium, is a pattern that returns changed, and a Meridian analyst hears that every day in the courses of the Long Shelf. The resemblance was never in doubt. What Sixth Course would not do was let a resemblance stand in for an address: a pattern that returns is not a pattern that answers, and no analyst of the Long Shelf would call something speech on the strength of its rhythm alone. The finding said resemblance, not authorship, and the council filed it without complaint and without surprise, in the manner the Administrator-Voice's own account gives the Long Shelf, a people who never expected the sea to answer a question quickly.

Sixth Course lives under an administration the Long Shelf did not choose. The deep-shelf mineral beds the Cerebraun Hegemony extracts are not an abstraction to an analyst who listens to the shelf margin for a living; the beds are a place in the city's hearing, and the work of extraction has a sound in the lattice that the council's objections, filed more than once through the Administrator-Voice and recorded and not acted on, have not changed. The record does not hold Sixth Course's own view of the extraction, and the Long Shelf's own discipline is the reason: when the council petitioned to be consulted on the Sentinel, it insisted the consultation stay narrow and keep clear of the extraction dispute, so that the Sentinel could not be read as a bargaining position by either side. Sixth Course is recorded as having argued for that separation inside the council's own deliberations, on the analyst's ground rather than the diplomat's: a question answered to gain something else is a question not answered.

What the Long Shelf's people call themselves, their own name for their world, and their own name for the Hegemony, the record does not hold; the survey's names are the ones on file, and the record keeps them as the survey's. No pronoun system is declared for Meridian's people, and this page uses the name throughout, as the record does for the Cerebraun. How the Long Shelf's analysts rendered the Sentinel's telemetry into their own medium, what instruments a reef-city keeps and whether the translation ran through the relay station's channel or the council's own, the record has not established and does not guess.

Whether the Sentinel is Meridian-built, older than the reef-cities, or unconnected to Meridian entirely remains unresolved, and Sixth Course's finding is part of why it remains so honestly. This page leaves it where the chapter left it.
