A Wisconians Guide to Potestatem: Potestatem.

Welcome to Potestatem Terran! You're likely afraid, tired, and wondering how you found yourself on a strange new planet with an asteroid ring orbiting it. Don't worry, you've found this book, which means you're at least 15% less likely to die. We Wisconians were once also from Terra, so I have written this guide to Potestatem in a way in which will help you understand it. Note, this is only a brief guide and generalizes greatly so expect variation!

Geography: Potestatem is separated into two major landmasses. Simply referred to as the northern and southern continents. The northern continent is a cold and desolate place. You'll probably never go there, and if you do, I'd bring blankets. The southern continent is large and has many diverse places. It is a continent that puts Eurasia to shame.
Not only is the southern continent massive, but it is also a land of extreme biomes. The Foisham Jungle spans thenorthern section of the continent. The Jungle is a massive and mysterious place. Below the jungle is the Dawn Mountain Range, a line of mountains that would span from Tokyo to London if moved onto Terra. Other notable geographic regions are the great Hazfen Desert, the small but important Ydnac Lond, the rolling grasses of the Arcane Vale , the humid lands of the Snaleshi Swamps and many others. These lands all posses unique geography, so feel free to research more if you wish.
Potestatem also has 4 moons; from smallest to largest: Fluloris, Fulgring, Cramen and Coigus. The planet also has an asteroid belt surrounding it.  
Cultures: There are many cultures in Potestatem, with many regional variants. The most widespread culture is Perisian, which you can think of as a cultural equivalent to medieval France. Thanks to the Perisian Empire, this culture is basically everywhere to the point that their language is just referred to as common. Many of the other cultures found throughout Potestatem are similar in some way to cultures that existed on Terra but they also have many unique aspects. You will need to do independent research if you want to know more about a place or people.
One culture which also needs to be mentioned is Wisconian. (The culture I'm from!) Wisconian culture is derived from a magical accident that occurred during the later part of the second era, which caused a town from Wisconsin to be teleported to the area now known as the Wisconian Plains. This has caused Terran cultural signifiers to become somewhat commonplace in some quarters of Potestatem - if you hear someone making "yo mamma jokes," you've likely found yourself a Wisconian!
Religion & Godhood: Unlike the standoffish gods of Terra, Potestatem is brimming with colorful divine faces. The most preeminent divine institution is The Temple. In which the Thirteen Temple Gods rule according to their strange rules. You should also know, these gods often sponsor champions to do their dirty work. These champions are known as Slivers of Divinity; if you're unlucky, you might become one too!
Multiverse: Potestatem is, like Terra, one among many worlds in the multiverse. You should be aware that their are also other planes of existence as well!
