Wind Flutes are enormous metal or wooden pipes, like musical instruments, that have holes and valves inside.
They only produce music when wind blows through them. Nature makes the music.
The Caelians and Dillians believe that these beautiful natural melodies calm and put Caelius in a good mood. On Caelia, there is an entire valley dedicated to these Wind Flutes. On Dillos, on all of their floating cities, they have these Flutes.
Wind Flutes can be miles long and are masterfully constructed.

Dillians are a bit Buddhist and believe in non-vi.olence, but the do believe in Caelius.
Caelians believe in the natural order and that the strong survive and value honor, skill and family. They utter believe in Caelius's existance.

Caelius has acually been seen on Caelia. There are even a few pictures. He has only been seen after an enormous storm called a Caelstrom, which is much like a hurricane, but with winds blowing in opposite directions at thousands of miles an hour.
He is often seen glowing light greenish/white.
Dillians and Caelians do not recognize other gods besides Caelius. Other planets of the Daelian Empire do, however.
