Structure Cycles

## The 10 Year Cycle

The Realms of Oroi-Ullon grow hotter and colder in a 10 year cycle. This is controlled by the output of heat from the small star at the center of the megastructure. This heat and light generated from this star, in turn, is controlled by the flow of black and white magic which is let into Oroi-Ullon through the great wells that penetrate its shell. The rate at which these magic particles are let in are kept in an oscillating balance. In an alternating cycle of 10 yun each, white magic gets released at a greater rate and black magic released at a lower one, and vice versa.

There is this back and forth instead of a constant and steady stream of the white and black magic so that during the lower flowing periods, the apertures which let the flow of magic into the world can be repaired. The apertures which let the white magic in will naturally accrue material on its walls over time as a natural byproduct of the white magic. This would gradually cause the aperture to grow smaller and interfere with functions if let be. The walls of the apertures which let the white magic in will naturally decay and erode over time as a natural byproduct of the black magic. This would break down the structural integrity as well as interfering with the other functions.

## Daily & Seasonal Cycle: Vaū

Both the day, season, and yearly cycle is determined by the turning of the Baiurs. A single rotation is equal to a single day, and is what causes the appearance of the sun to rise and fall across the sky. However, the Baiurs do not just rotate along their axis, but they actually go in a corkscrew type pattern, slowly moving to the side with each rotation. At the anchor points of each edge of Vaū that connect them to the vertices, there is a portal that connects all the edges, which have a true form as one long single cylinder.

Throughout a year an individual Baiur will move from one vertex of Vaū to the next, and caused by this, the Baiur's distance to the sun changes as well as the angle at which the sun's light reaches it. When at the mid point between two vertices, the Baiur will be at a perfect 90 degree angle to the sun, and thus the light from it will travel through the least amount of atmosphere. But when a Baiur is right next to a vertex, the Baiur is at a more acute angle, causing the light to need to travel through more atmosphere to reach the surface. This is what causes the changes in temperature throughout an individual year, and thus the seasons.

* Long: Rising Season - Verdin
* Short: High Season - Goden
* Long: Falling Season - Kormin
* Short: Low Season - Soien

The high season is the single week when the sun is directly overhead. The low season is the single week when the sun vanishes as the Baiur sky is covered doing its transition through the portal at the vertex. The rising and falling seasons are the long periods in between as the Baiur moves away and then back toward a vertex.

### Shadow Cycle:

All things have shadows, but for most, they are abstract and vague in their form. For sapient inhumanoid creatures, their shadow will echo the form of their master. For some humanoids this echoing of form also happens. More commonly though, humanoids have shadows that take on the form of inhumanoid animals. Depending on when they are born, the form of their shadow will differ. The season decides type by domain, aboveground for rising season, underwater for falling season, sky for high season, and underground for low season. The month decides type by diet, carnivore for first month of a season, omnivore for second month, and herbivore for the third month. If a sapient humanoid is born on a shift rather than a month, they will have a shadow that takes the form of the apex / noble animals. Drakes for rising shift, Leviathans for falling shift, Dragons for high shift, and Wurms for low shift.
