I would say that it's because they're so dry. They burn easily and the sun really stings them. The fact that the sun came from a hole to Aetherius has nothing to do with it - the sun's still hot.

I don't think Bethesda had a reason, though.

(although, I've always thought that not everything written about the Gods is true in TES. Like, yes, supposedly the moons are Lorkhans corpse and the stars are holes to Mundus, but we used to think that stars were holes to heaven too, but now we know they're not. Hmm... maybe that's why there's been no tech advance for several thousand years. Since Gods exist, they blame everything on Gods. does that make sense? Aaaanyway, back to topic. yeah)
