Cosmology
From Arcis Wiki
The world of Arcis is, like earth, a large corporeal object of matter adrift in a kind of void, with many recognizable characteristics (weather, oceans, continents, civilizations anthropomorphic peoples etc.) However, the details beyond that diverge greatly from the traditional concepts of a universe. The "planet" itself is toroidal, as opposed to spherical, and has two moons: Belmea and Solstea. The void in which is drifts bears enough visual similarity to the universe of earth so as to be mistaken for it at first glance, but in actuality is different in enough ways so as to be substantially different.
The Torus

The world of Arcis is shaped like a Torus with an outer circumference of nearly 30,000 miles.
