The Infinite Plane

Summary
The Infinite Plane is the overall universe of the setting. The Infinite Plane is differentiated from other realities by the lack of 'matter thinning' in its cosmological expansion as well as the presence of magic. Since the Calamity, most of the Infinite Plane has been rendered inhabitable due to the shifting rules of reality and the resulting cataclysmic anomalies therein.

Ancient Times
The Infinite Plane once boasted a number of consistent galaxies and a relatively unchanging (and handsome) observable universe. As a result of its relative calm, many civilizations rose to power and prominence on a variety of different planets. Because of the suggestive nature of reality, most species scattered throughout habitable space came to be familiar with magic to some extent during this timeframe.

The Calamity
For more information, see Calamity.

The Calamity was the turning point for the Infinite Plane, making every inch of it all-but-hostile towards life and stability. Many stable fixtures in the universe could no longer be taken for granted. The flows of time and space were thrown into flux; galaxies could live and die in the blink of an eye. 95% of all life in the universe was practically erased.

Most residents of the Infinite Plane have no idea how or why the Calamity came to be. As the vast majority of the population in 11003 CC have no frame of reference, very few people question what brought on this change. The following information is true, but not widely known within the canon of the universe. As such, it's been collapsed. Cataclysmic anomalies began happening as a direct result of the universe reaching the 'limit' of space which was afforded to it and coiling in on/erasing itself in an effort to continue its unstoppable growth. The Infinite Plane is a living organism which operates off of a basic instinct to grow. Its sapience is unknown, and perhaps unknowable.

The Modern Infinite Plane
The Infinite Plane remains dangerous to this day.

However, the establishment of Habitable Space by the Council of Shepherds marked the beginning of the Counter-Calamity era— an era which began 11003 years ago. Habitable Space is the one area in all of the Infinite Plane in which the rules of reality are kept remotely under control, allowing for the consistent existence of a small galaxy housing the Gaska Systems.

In modern times, methods have been developed for traversing and surviving the calamitous space of the Infinite Plane, with many people finding making their homes in the Outskirts of Habitable Space. The Voyager Corps exists for the express purpose of exploring and familiarizing itself with the Infinite Plane and its many trappings.
