Jahlee goes to the trouble of saying they can't be without air for too long
(at the same time, that implies they can survive a bit of airlessness
between Green and Blue), and that's why Quetzal didn't get to the Whorl that
way. If the whole space-crossing thing is a lie, it certainly is one with a
lot of detail.
