layers of air

Aiwenórë in Quenya, or simply called "Bird-land", is the lower region of Vista, the lower layer of the atmosphere, where birds may fly and breathe. I so wish I could shapeshift and join them, but alas, my name is not Elwing

"Fanyamar or the Cloudhome, is the upper layer of Vista, where clouds form before the world was changed. I remember the thick curtain-like clouds that covered the peaks of the Echoriath in Beleriand. In Eriador... perhaps only Hithaeglir is a distant reminder of that... I wonder what it would feel like to dive in them... oh by the way, doesn't that cloud look like a soaring eagle?"
