The Secret Of Sound

The sound of the wind?

They were now flying at an altitude of several hundred meters. The demon falcon flapped its wings in the shifting clouds, and the howling wind was constantly assaulting their skin.

Angor tried to think of his previous experience. There was nothing wrong with the sound of the wind in his memory.

A stable wind blowing sound could not be used to trigger nodes for illusions, so the Melodious Illusion deployed by Sunders had nothing to do with wind.

Angor frowned.

Was there any other sound apart from wind?

Bird chirp maybe? No.

The only bird in the vicinity was the demon falcon they stayed on. And it did not make any noise aside from the painful scream caused by Angor's cantrip.

Clouds? Can't be.

Clouds did not make much sound in the sky. Sunders probably could do something to make them work, but Angor did not believe that his professor would make the test so difficult.
