The direction of the sun at noon is always the same. In summer, the sun will be high at noon and in winter it will be low, but the direction will always be due sunward.
In our world, the sun rises due east and sets due west on the equinox. The angle between east and west is 180 degrees.
In Edgewhen, this is not the case. On the equinox, the sun rises 45 degrees left of sunward and sets 45 degrees right of sunward. Considered in earth terms, the sun always appears to be between due southeast and due southwest.
In summer, you can see part of the bottom half of the sun’s orbit. As it rises, it will appear to move left a little bit, until it reaches the leftmost point of the circle. Then it will move right as it continues its arc through the sky. As it sets, it will move to the left a little bit before it sets below the horizon.
Lithward and Moonward
The other two heavenly bodies have similar orbits of similar size. Due lithward is 120 degrees to the right of due sunward. Due moonward is 120 degrees to the left.
Like the sun, the moon and the lith vary no more than 45 degrees from the directions defined by their pivot points. This means there are always at least 30 degrees of horizon between any pair of heavenly bodies.
Sunaway, Lithaway, and Moonaway
Each cardinal direction has an opposite direction. For example, sunaway is 180 degrees from sunward.
Sunaway is between lithward and moonward. The orbits of the heavenly bodies are such that the lith is always to the left of sunaway and the moon is always to the right.
Maps vary from culture to culture and from mapmaker to mapmaker. Sunward is often depicted as up. However, along rivers that flow sunward, some mapmakers prefer to depict sunward as down.
The lith and the moon also have an analog to seasons. The moon is on a 7-year cycle. For half the cycle, it appears to orbit about a point below the horizon. For the other half of the cycle, this pivot point is above.
The lith has cycle that lasts 143 lithics. This cycle is difficult to see because the pivot of its orbit rises or sinks only a few degrees. The time between the rising and setting of the lith is not always precisely 1 hour and 20 minutes, but it is consistent enough for most practical purposes at Edgewhen’s technology level.
