Foreword by a Chronomaestro of the Theastone Lexicanum
The Hyuron measures his life in the frantic ticking of a clock, the Drâihari in the slow drip of blood, but the true scholar measures it by the grand, silent turning of the heavens. To understand Nhera, one must first understand its celestial cadence. Our world does not follow the simple, brutish rhythm of a spinning top. It moves with the subtle grace of a dancer, its days a slow tide of twilight, its cades a complex and beautiful symphony sung by three warring moons. This is the Great Cadence, and to learn its verses is to begin to understand the very soul of our world.
Due to Nhera's lenticular shape and its significant axial "wobble" precession, the transition from light to dark is not a swift, sharp line, but a vast and creeping band of twilight hundreds of miles wide, known to poets and sailors as "The Veil's Edge." A full rotation of the realmstar, marking a complete cycle of light and shadow, is known as a Turn.
Passages: A Turn is divided into four primary "Passages," marked by the position of Asra in the sky: High Passage (midday), Fading Passage (dusk), Low Passage or the Gloaming (midnight), and Waking Passage (dawn).
The Nheran equivalent of a month is a measure of the seasonal "wobble" of the planet as it orbits Asra. This causes the great shadow of the Veil's Edge to appear to climb and descend across the faces of the world.
The Veil-March: A single "March" is the time it takes for the shadow's edge to travel from its highest point on one face of the lenticule (its Ebb-most point) to its lowest (its Flow-most point).
The Marches: A full seasonal cycle is composed of several Marches, their number varying by cultural tradition, but the Arunean Imperial standard recognizes twelve Marches to a full year.
The Nheran tidal system is a complex, chaotic, and deeply mystical science, governed by the warring gravitational pulls of the three moons: Rend, Raen, and Asur. A master navigator must learn to read the specific "mood" of the tide, as each moon imparts its own distinct personality upon the water.
The Raen-Swell: Governed by Raen, the large, stable moon. These are the great, predictable ocean tides, the reliable currents upon which commerce is built.
The Rend-Tide: Governed by Rend, the fast, chaotic moon. These are sharp, violent, and treacherous tidal surges that can create sudden squalls and deadly rip currents with little warning.
The Asur-Pull: Governed by Asur, the slow, dark moon. This is not a surface tide, but a deep, almost invisible undertow. The Asur-Pull is the most feared of all, a silent current that can drag a ship's keel into the Fathom's grasp.
The Conjunctions: When the Heavens Align
The true danger and power of the tides are revealed when the moons' orbits align, creating events of profound astrological and physical significance.
The Silent Neap: When the moons are in opposition, their pulls cancel each other out, creating an unsettling, dead calm upon the ocean, a time when sailors whisper the Fathom is listening most intently.
The Triune's Gaze: A rare, full conjunction of all three moons. This creates a tidal surge of mythic proportions, a catastrophic event that can reshape coastlines and is seen as a time of immense, world-altering destiny.
A Nheran year is not a simple solar orbit. It is a vast and complex celestial cycle, marking the time it takes for the intricate, interlocking orbits of Rend, Raen, and Asur to return to their original, perfect alignment.
The Great Cadence: The formal Valari term for this full year-cycle. To the Arunean Imperia, it is often called a Full Cadence or simply a Cade. In the harsher tongue of the Drâihari, it is a Renduar'n, or "Blood-Count."
The Celestial Chart: Nheran calendars are not simple squares. They are magnificent, circular celestial charts, part-astrolabe and part-calendar, showing the spiraling, interwoven paths of the three moons.
A master Chronomaestro can use this chart not only to mark the passage of time, but to predict the very mood of the sea and the nature of its tides, foretelling periods of calm passage or dangerous conjunctions for a Cadence to come.
