There is a city of glass, suspended in the air by a mixture of magic and technology.
It is populated by a race of animated glass golems, who feed on magical residue.
The golems were made by a race of ant golems created by ancient beings.
Magic is purely elemental in nature, composed of the elements EARTH, FIRE, WIND and WATER. There is also a fifth element, believed to be lost, known as MUSIC.
People who practise the fifth element are known as Musicians, and being to various groups known as bands.
All but one are ghosts, cursed to eternally wander the world. It is said that these ghosts meet once a year at the venter of the planet to have a contest of Music, known as the Battle of the Bands.
The only still-living Musician is known as the Lady of the Serenade.
No one know who or where she is.
Music never actually existed, and is an element form another universe. Bands and Musicians, are travellers from interplanar swirl who use elements of their original planes.
This inter planar swirl occurred only because of 'The Leak' which occurred when a god peed his pants.
The Leak was felt by great elementalists of this world.
