The Living Chart Tradition

The Directorate maintains an extensive body of navigational charts, star-course tables, and tide records, held primarily at the Grand Anchorage and copied in part to major way-stations along the route back toward the mainland. Unlike a fixed archive compiled once and preserved, the tradition is actively maintained: every voyage returning from a route already charted is expected to note discrepancies, and every voyage into less-familiar waters is expected to contribute new observations, reviewed and incorporated by a small standing office of chart-keepers at the Anchorage.

This living-document approach has produced charts of the strait, the routes toward the Indian coast, and the waters east toward the archipelago that are, by most accounts, considerably more detailed and more frequently corrected than anything available to other regional powers, including the Restricted Factory, whose own charts are understood -- through channels no one at the Anchorage will specify precisely -- to rely partly on informal copying from Directorate sources.

The chart-keepers' office is unusually candid, by the standards of most Directorate departments, about the limits of what it knows. Official charts note explicitly which coastlines are drawn from direct observation and which are drawn from secondhand report, and the office maintains what chart-keepers themselves call the "far margin" -- a set of notes on waters no Directorate vessel has ever charted directly, including at least one distant landmass referenced only in secondhand accounts from traders who claim to have heard of it from further traders still, its existence and location unconfirmed by anyone Malacca's chart-keepers consider a reliable source.

Whether that landmass is real, misdescribed, or simply a distortion accumulated across several tellings is a question the chart-keepers' office has left formally, deliberately open on every edition of the far-margin notes issued for the past thirty years.
