Greenward

Greenward is a single ring in a high circular orbit above Verdance, holding two hundred and forty people, most of whom will never set foot on the world eight thousand kilometres beneath them. It is the human half of the reciprocal instrument the Federation of Sentient Beings and the Star Rangers concluded within a generation of first contact, and whose other half is the Guest Ring.

The shape is worth setting out plainly once, because the rest of this entry is about where it distorts. It is a mirror: in the Calyx System, Greenward, a human ring above Verdance, home world of the Verdani, with the Federation as host; in the Bríd System, the Guest Ring, a Federation ring above Drithane, a charter world of the Celtic Union of Planets. Between the two rings stands one document, and instrument is that document's word for itself — the drafting sense, a paper that does something, not a device that measures it.

The instrument is short. Each party maintains one orbital presence at a world of the other's; neither descends; either may withdraw the invitation, on notice, without stating cause. It is a page and a half, it has never been amended, and both parties describe it as symmetrical.

Where the Symmetry Stops

It is not symmetrical, and the record says so in three places without ever proposing a fix.

The signatories are not the same kind of thing. The Federation is a cooperative of worlds and can offer one. The Star Rangers, by their own charter, hold no planetary or large-habitat jurisdiction — entry is by invitation and they leave when it is withdrawn, which is precisely the clause that makes them trustworthy and precisely the clause that leaves them with nothing to trade. The Rangers could not offer a world in exchange for Verdance orbit because the Rangers have no world. What actually happened is that the Celtic Union of Planets issued the invitation over Drithane and the Rangers brokered it. So one side of a two-party instrument has two parties on it, and the document does not mention this.

The non-descent clause is one sentence covering two different facts. Nobody from Greenward may go down to Verdance, and nobody from the Guest Ring may go down to Drithane, and those read as the same restriction. They are not. Verdance carries four native civilisations under a confederation that did not sign anything, and the bar there is protocol — Greenward's people are equipped to land and are not permitted to. On Drithane the bar is chemistry and cold, and no permission would help. One rule, two reasons, and only one of them could ever be relaxed by anybody's decision.

The costs do not match. Maintaining a pressurised ring in the Calyx System is a routine expense the Federation absorbs as host. What the Federation maintains over Drithane is not routine and is not comparable, and the Union's share of it has been raised at every review. The reviews have not changed it. The usual answer given is that an instrument which had to be fair in its arithmetic would have taken thirty years to write, and the point of this one was that it took four months.

What It Is Actually For

Not diplomacy: the Federation and the Rangers had a working relationship, a material-support compact, and no dispute worth housing. What Greenward does is duller and harder to arrange, which is why it needed an instrument at all. It puts a standing human presence where Federation ordinary life happens, indefinitely, with nothing to negotiate and no term to expire — and it accepts the same in return.

The stated reasoning, from the Ranger side and preserved in the compact file: two parties who have only ever met each other's delegations know each other's best behaviour. Two parties who have lived above each other for eighty years know something else. The Federation's own minute of the same session is shorter and says approximately the same thing, and the Archive files them together on the grounds that the agreement is more interesting than either version of it.

The Watch

Greenward keeps one duty nobody wrote into the instrument. Verdance's confederation is loose, its four civilisations are on one world, and the ring can see all of it at once — which means that from the day it opened, Greenward has been the only place from which certain planet-wide changes are visible as they happen rather than as they are reported.

It does not report them. The instrument gives it no standing to, the Rangers have no jurisdiction that would survive the attempt, and the confederation has never asked. What Greenward does is keep the record, date it, and hold it against the day somebody with standing does ask. Whether that is restraint or an evasion of responsibility is an argument the ring has had with itself for eighty years, and it is not settled there either.
