Natural Astronomy (sage study)
Natural astronomy is a sage study in the field of Earth & Sky, concerned with observing and understanding the relationships between the heavens and the world below. Unlike the clerical sage study of Astronomy & Astrology, it does not seek meaning through divine influence or omen, but through the regular movements of celestial bodies and their effects upon the earth. The study includes the reading of the sun, moon, stars and visible planets as they relate to direction, season and the passage of time, together with an awareness of how these patterns correspond to changes in weather, terrain and natural conditions. Mathematics, including algebra, geometry and trigonometry, supports this knowledge, though much of it is derived from sustained observation and familiarity with the natural world.
In practice, studying the sky is carried out by fixing the movements of the heavens against known points upon the earth, so that their courses may be recognised and compared over time. Observation is made from chosen places where the horizon or surrounding features — hills, trees, buildings or the line of the sea — provide stable references against which the rising, setting and passage of celestial bodies can be marked. With observatories, these reference points are not merely found but made, with structures raised to establish clear and deliberate lines against which the heavens may be marked. Such observatories provide fixed edges, angles and alignments, allowing the watcher to set the rising or passage of a body against a known point with greater certainty. By these means, the sky is given a frame, so that its motions may be compared and recalled with greater exactness than the natural horizon alone affords.
By returning to the same place and repeating the same observation on different days of the year, the watcher learns the expected course of each body and can recognise its position rather than by abstract measure. The sky is therefore read not as an isolated expanse but as something set in relation to the world below, its movements understood through their constant agreement with the ground from which they are seen. Characters with this knowledge essentially have star and planetary tables memorised, enabling them the sage abilities attached to the study.
Sage Abilities
The sage abilities below are those acquired by a character through the study, according to status.
Amateur Status
- Navigation: setting a course over land or sea, derived from the position of the sun or stars. A skilled navigator can determine their precise location even in unfamiliar territory, using celestial bodies, prevailing winds, and natural landmarks to adjust their route. This ability also includes an understanding of seasonal shifts in star positions, variations in ocean currents, and the subtle changes in atmospheric conditions that signal shifts in weather or terrain.
- Recognise Heavens: grants the character a deep knowledge of the celestial sphere, allowing them to accurately identify individual stars, constellations, nebulae, planets, asteroids, meteors and comets. With this ability, the character understands the precise movements of the sun and moon, enabling them to track their cycles and seasonal variations.
- Timesense: enables the character to accurately judge the time of day when above ground and with a clear view of the sky, within 15 to 20 minutes.
Authority Status
- Predict Meteor Events: Grants the ability to predict strength and influence of meteor showers, affecting druidical magic use.
