Lucerne’s primary setting, Thurn, is an important part of the game. Many of the classes, their abilities, items, spells, and more refer to some part of this world. Think of it as a “default setting,” with just enough left open to interpretation and improvisation to fit most game master's needs.

Thurn is a world shaped by its own history, gods, and rules of nature. There are a few key things that separates it from our reality.

First, is the influence of the magical substance known as myst. Myst, in short, is a nonphysical magical energy of sorts that permeates throughout all things, in varying amounts. Powerful magical objects and spells coalesce more myst around them. Living things, too, carry myst with them innately.

Second, is the presence of higher beings, such as gods, demons, and others beyond our comprehension. These entities exert their influence upon the world, and are often at odds with each other. Some major events, even in recent history, where the gods have shown to be more passive, are shaped by their wills and desires, in some manner.

Thirdly, is the world itself. Deep below the surface lies entire ancient civilizations, unfathomable creatures and darkness beyond measure. High above the clouds, at the heights of towering mountain peaks, lies the divine realm; a place where life and harmony are held chiefly. There are great wastelands that were once ancient city capitals, cities that have outlived their creators, and things from worlds beyond, seeking something unknown. Indeed, Thurn is full of much to discover, and even more to uncover.
