Solid-clouds

The info here is in a state of flux, everything can be changed!

Not sure what solid-clouds are yet. They are more solid than real world clouds, but they don't have to be much more solid. Perhaps ranging from the firmness of new-fallen snow to that of springy moss. It could be very difficult to tell also, making walking on solid-clouds treacherous. Sky Vines grow into, and from, solid-clouds.

I was thinking more like the feeling of the water saturated beach sand meets snow. so it withstands initial impact well, but motion makes it give way.

Questions

• Where do solid-clouds come from?
• Do they have any special properties?
• Do certain creatures or Fay eat solid-clouds?
• Are they changeable and transitory like real clouds?
