Trivium is a world of magic and wonder. It is the crossroads for the multiverse.

Mana can be found everywhere, be it in the trees, rocks, or even the very air itself. It is this energy that gives shape to the magic of the world of Trivium. Two of the greatest sources of magic are multiple leylines and the 108 wellsprings of magic. While the leylines are fixed currents of mana traveling the globe, the wellsprings of magic take the form of various objects. Each wellspring contains primordial magic in different fields. They are unable to leave Trivium, for if they would ever do, they would break. If that were to happen, a new wellspring would be formed in Trivium to take its place, its location chosen at random.

The veil between the worlds is thin in some areas, where breaches across time and space called rifts form. These connect Trivium to a myriad of other worlds. However, travel isn't always easy. The rifts themselves are invisible. While some are stable, always linking the same two points and times, others are in flux, shifting destination. While you can always use a rift to enter Trivium, it's not always a simple task to return from whence you came. For example a rift that leads to modern day Japan one hour could lead to medieval Europe the next. There also exist one-way rifts that cannot take you back.

The rifts are responsible for Trivium’s considerable diversity. Many races from unrelated worlds have crossed over into Trivium with varying degrees of success. Some races live in harmony with each other, settling down and blending together. Others make war, trying to conquer those already living there. There are even those who pillage the rifts, stealing resources and abducting the denizens of the other worlds. And, of course, there are the monsters that migrate over and multiply. Many races have dwelled with in Trivium for thousands of years and have long forgotten that they originally came from another.

The influence of the different worlds has caused the different nations that make up Trivium to advance at different rates. Some are very primitive, while others are quite developed. This is aided by the difficultly of travel, thanks to monsters and bandits. There are tribes that rely solely on brute force, those who craft tools of stone, and those who work with metal. In some parts of the world, magic has even become a part of everyday life, used for everything from lights to cooking and even war use, while others see it as a rare art. As a whole, the level of the world is generally medieval.

Trivium is also host to several different types of government, each of varying size. The larger nations often run on a monarchial system, while smaller villages might hold elections or appoint the village elder, and some have submitted themselves to the rule of a single, immortal leader such as an elf, demon, or dragon. These are only a few styles they might take. There is no real requirement in size, as a nation could consist of just a village with a few hundred people. Whatever the size, there is always the risk of a civilization's destruction. Many have fallen prey to monsters, bandits, or more powerful nations. However, new ones always seem to sprout up.

Magic and chi are abilities that can be learned, but there are also those that cannot. Although rare, some people possess powers not normal to their species. Some are hereditary, passed down through certain bloodlines, while others are random, seemingly granted at birth without reason. Additionally, powers can be granted by deities or items of great power. These powers can range from shaping the elements to sensory, or even something as simple as putting a spot on a wall. Unlike magic, it generally requires no mana or incantations.
