Ganymede is a a world ruled by forces and energies both known and unknown.
Each major culture on Ganymede has some concept of 'magic' but despite all magic deriving its power from what appears to be the same underlying principles,
there exists no unified magic theory that can describe all magic. There are only various disciplines which understand magic in different ways, each of
specializing in specific effects.
These disciplines range from the Qing Arcana of Ziani which specializes in controlling the latent energies of the human body to achieve superhuman feats,
to the Nekarken Arcane-Standard (NAS) of Galeral which has a scientific-basis for the understanding of magic, allowing those who use magic on Galeral to achieve
much more complicated magical effects. Of course, The NAS is incomplete in its understanding of magic, such questions as "Where does magic come from?" or even
simple questions such as "Why are lead and brass objects naturally resistant to magic energy but not any other basic metals or alloys?"
Obviously, conjecture is often proposed for these questions but they will always fail as the NAS is about as accurate as Early-Newtonian Physics.
For being comprehendable and freeform, the different continents of Ganymede are virtually completely seperate from each other, in world this is because of 'Great Barriers' which surround each continent.
As such, further reading will refer to specific continents.
