Erde is a planet dominated by music. It is not God that causes good to happen, but
the Harmonies. Likewise, it is not the Devil that causes evil, but
Dissonance. On Erde, it is music that ties everything together, plants and
animals, rocks and trees, organic and inorganic ... and what's more is that Erde's
intangible fabric of music is one that can manipulated through the use of more music;
you could almost call it magic.
This magic can be used in two forms, each with its own uses: darksong, and
clearsong. Darksong, for example, is the manipulation of living things or things
that were once living, while clearsong deals with inanimate objects. Too much use of
darksong, however, has a price; frequent darksong users often suffer from double vision
and headaches after each use, ailments that increase in duration and intensity as time
goes on.
Although no magic can be wrought by instruments alone, minor feats can be
accomplished by the sole use of a song, sung by a sorcerer (singer). Greater magic
is usually only possible with the accompaniment of Players with instruments,
although it has been know to happen that powerful sorcerers/sorceresses could do them
with great effort and the price of extreme exaustrion.
