Editing Control of Navigation (section)

==Priestesses' summary==
Here is a clean in-world document, written as if it were produced by the Priestesses themselves and given to Navigators. It avoids modern scientific language and frames the knowledge as sacred.

====The Ordering of the Heavens for the Guidance of Ships====

''Copied in the Temple of the High Observatory for the Guild of Navigators.''

The seas are wide and without boundary, and the winds are changeable. Therefore the gods, in their mercy, placed signs in the heavens so that those who travel upon the waters might not be lost.

The Sacerdotisa, whose duty it is to observe the movements of the sky, keep watch over these signs. From the highest towers of the temples they mark the rising and setting of the stars, the wandering of the constellations, and the turning of the seasons. These observations are preserved in the temple records so that the wisdom of many generations is not lost.

From these records are prepared the Star Charts of Navigation, which are issued to the captains and navigators of the fleet.

====Concerning the Stars====
Certain stars are steadfast and serve as guides for direction. By them a navigator may know the course of his ship even when no land is in sight.
Other stars rise and fall with the seasons. Their appearance in the night sky tells the wise navigator what month of the year has come and what winds may soon follow.

The constellations are the signs by which the heavens speak. Their forms are marked upon the charts so that sailors may recognise them easily during the night watches.

====Concerning the Charts====
Each chart contains:
* The principal guiding stars.
* The shapes of the sacred constellations.
* The seasons in which these stars appear most clearly.
* Tables showing the proper height of certain stars above the sea when a ship sails at known latitudes.

These charts are copied upon treated parchment so they may endure the damp air of the sea. The stars are marked in silver ink, and each chart bears the seal of the temple to show it has been properly prepared.

====Concerning the Duty of Navigators====
Navigators who sail the ocean routes are entrusted with this knowledge. They must study the heavens faithfully and compare what they see with the marks upon the charts.

Before a great voyage begins, it is customary for the captain and navigator to attend the temple, where a Sacerdotisa will bless the chart and commend the ship to the protection of the gods.

Thus the ship sails not by chance but by the ordered lights of heaven.

====Concerning the Authority of the Cregans====

Because the heavens change slowly from generation to generation, the Sacerdotisa continually renew the records of the stars. From time to time new charts are prepared so that navigators may sail with the most faithful guidance.
Therefore the Guild of Navigators maintains its bond with the temples, returning regularly to receive corrected charts and the blessing of the observatories.

In this way the knowledge of the heavens is preserved, the seas are crossed safely, and the will of the gods is honoured.
