The name Illystra is known only to a very few of those who travel between worlds...
Each world exists in its own self contained realm. Each realm floats on its own tier, sovereign and unseen by others. Illystra has an infinite collection of realms that compose and make her up. While many of these places have many items in common, the only true commonality among them are the Primordial Deities.
Laws of Physics, Laws of Magic, Systems of Faith, and other aspects are unique to each realms. Travel between realms is almost no-exsistent, but some pathways between realms do exist. They are extremely hard to find and even harder to open. Only a few know of the existance of these pathways, and how to use them.

These Primordial beings existed before the birth of any civilization...
Every 20 to 23 years the tear phase of Lunater turns blue and this lasts for a week, children of any race are not considered adults until they acknowledge themselves and receive her blessing. Long lived races usually only seek acknowledgement after several such occasions.
Every 10 years like clockwork Ignater shoots arcs of fire across the sky, burning those caught in the open beneath its fury. This goes on daily for a week. Fortunately, it is tracked and monitored, and few are foolish enough to be out during this time. Some, however, believe if it can be survived, great blessings will befall them.
Storms by their very nature are chaotic and unpredictable, as are the ways of Tempest. People tend to stay inside when Tempest appears to be his most violent. When the lightning turns red it heralds a time of great change, as the cities and civilizations have been turned to dust in this phenomenon. Fortunately, this is mostly a topic of myth and legend as there are no records of it happening in thousands of years.
Solsta is unique among the Primordials as most people see her as 4 aspects, not the 3 the other Primordials are seen as. She is also seen as the most calming. Many people give thanks to her daily as they prepare or eat their meals. Other than the changing of the seasons there is no natural event that people attribute to her.
