Vex Cartographers Guild

The Vex Cartographers Guild is a chartered drafting body of the Upper Middens, incorporated on 14 Pluvine 604 by warrant of the Third Concordance and headquartered on floor 2288. It is the Tower's only guild whose maps are considered authoritative while the mapmaking is still in progress: a Vex chart is admissible in filings before the survey has closed, a distinction the guild has defended at length and at cost for two centuries. Its membership stands at forty-one cartographers and one door-warden; the door-warden's post is the older of the two offices and, by tradition, the better paid.

Charter and jurisdiction

The Guild was severed from the Guild of Formal Cartographers at the request of the latter's eastern benches, which found the Vex practice of issuing unfinished charts "cognitively expensive to the reader" and petitioned for separation. The Guild of Silent Cartographers supported the severance; the Guild of Precedential Cartographers opposed it on the grounds that an unfinished chart, once filed, becomes a precedent for every subsequent unfinished chart, and no one had counted those. The petition carried by nine seals to four.

The founding warrant is unusually brief. Its operative clause reads, in full:

"Let the Vex draw what they have not yet seen, and let it be entered as drawn; and let no surveyor thereafter complain that the ink arrived before the floor did."

— Third Concordance, Annex 9, clause 2

Jurisdictionally the Guild's remit covers "partial, prospective, and franked" surveys — a category invented for the purpose and never cleanly defined. The Architectural Cartographers' Guild has contested the boundary on three recorded occasions, most recently in 799, when both guilds claimed floor 3141 during a period in which that floor was partially collapsed. The Guild of Iterative Cartographers intervened on the Vex side, not out of sympathy but because the Iteratives wanted the dispute referred upward and needed the file to keep moving.

The practice of proximate drawing

Vex cartographers work from the near edge of the known. A survey begins at the last confirmed fixture — a lamp niche, a stair-foot, a surveyor's chalk line — and proceeds outward in a spiral, drawing as the space is entered. Charts so produced carry a spiral mark at the point where certainty ends; everything inside the mark is inked black, everything outside in a grey the guild mixes itself from lamp soot and a small quantity of sealing wax.

The grey is a technical matter and a matter of doctrine both. A grey line asserts that a wall is probable. The guild has maintained since 611 that probable walls are more useful to a reader with a lamp and a schedule than no walls at all. The Reality Cartographers’ Guild, which holds that a chart should record only what has been confirmed, has called the practice "an invitation to walk into a wall at speed" — a phrase from its 744 reply to the Vex petition for reciprocal citation, and one the Vex have quoted back at them in every correspondence since, usually without comment.

Recipients of a Vex chart are advised to treat the spiral mark as the boundary of usable content. The Advisory Annex to the guild's standing orders puts it flatly: a recipient who crosses the mark by more than forty paces should return to the last black line and begin again.

The Hall of Anticipated Floors

Floor 2288 holds the guild's principal and much-photographed possession, the Hall of Anticipated Floors: a long gallery hung with charts of floors that, at the time of drawing, did not exist in any inventory. Some have since been found exactly as drawn. Others have not. The guild keeps both classes in the same sequence and marks the distinction in the catalogue by a convention it regards as sufficient and no one else can see.

The Hall's most cited holding is the Anticipation of 651, prepared by the then-Provost Imre Vantal, which depicts a seven-sided landing with a well at its centre. No such landing has been located. The Expeditionary Cartographers' Guild spent four seasons searching for it and returned a report noting only that the search had been conducted thoroughly. Vantal's chart remains on display with the well unaltered.

The gallery is closed to the public on the ninth of every month for relamping. Visitors are asked not to touch the grey.

Dispute over the spiral mark

The guild's central doctrinal disagreement concerns the direction of the spiral. The founding bench drew clockwise, on the reasoning that the hand follows the lamp. A reform party, ascendant from roughly 680 to 738, maintained that anticlockwise marking better reflected the "recessive character of the unentered", a phrase from the Fourth Concordance whose interpretation has never been settled.

The Skeptical Cartographers’ Guild, in the years before its dissolution, cited the dispute as evidence that all cartographic conventions are arbitrary, which both parties found unhelpful and neither forgave. The question was put to the Librarians in 741 and returned unanswered, on the procedural ground that it had been put incorrectly. In practice both directions are now accepted, provided the chart states which was used; most state neither, and the discrepancy has produced at least two hundred misfiled surveys in the Lower Middens alone.

Index-Tender Vex and the present administration

Since the reorganisation of the auxiliary record in 812, the guild's chart intake falls under the oversight of Lysandra Vex, Index-Tender of the Cartographers' Auxiliary. Her surname's recurrence in the guild's own name is noted in the guild's history as a coincidence of long standing; the guild's ledger for 604 lists no Vex among the founding forty, and the Archivist's marginal note on that page — "no relation, again" — is the earliest occurrence of the Guild's name in its current spelling.

Whether the Guild takes its name from the town of Vex-on-the-Stair on floor 2201, from the obsolete verb to vex (to check a line twice), or from the founder's seal, which depicts a hand and a lamp and nothing else, remains an open question. The guild's own position, stated on the first page of every warrant copy it issues, is that all three are correct and that it does not propose to rank them. The Guild of Oneirometric Cartographers, which has published on the question, favours the seal. The guild has declined to respond to that publication, twice.

Current standing orders run to eleven leaves, of which nine are amendments. Members are reminded that a chart filed in grey is a promise, not a claim, and that promises are entered in the same ledger.
