If you check out the Canopy (by looking up) you can see that Silan is under several very large branches, but you can see the sky. Not a whole lot of leaves up there except on the trees that you can see growing on the branches.
The sun never sets and never rises; it flares...There is also a minor fact that the "stars" in the night sky are not (cannot be) distant fixed points. They are an atmospheric artifact.
The nebula is the nebula -- and yes it moves, circling through it's pattern every day..
- Points of light are not stars, and are not fixed points. (Are they holes in the canopy? This doesn't seem to match the artwork...)
- Silan does not rotate. (Hence the sun never setting or rising. And we can't be on the pole, since the sun comes from an angle...)
- Nebula is not a celestial body? Orbital anomaly? Since Silan doesn't rotate, the nebulous cloud has to orbit... OMFG!!! IT'S AN EXPLODED SPACECRAFT!! THE KARAVAN ARE STRANDED HERE! :D :D :D
Waaaaiiit... no way.... All those "stars..." They're not light-years away... they're surrounding Atys...

It's a massacre. They're the remains of the Karavan fleet?
This is too much... -_-
