Veder people

Some work for Veiland, my worldbuilding project.
It's always lots of fun !

Veder people live on the Breath.
The top half of their face is protected by a cartilaginous mask, allowing them to completely close their eyes and nostrils with a sturdy membrane.
The mask then morphs into a pair of hollow horns, which they can use to perceive incredibly distant sounds and vibrations.
Their language is sung, and they can hold full conversations simply by whistling.
