I created an article (marked as stub of course since it lacks a bit of information) about the weather in Cradle. I've mostly confirmed my findings that the weather in Cradle is hardly natural.

I decided to make this since it was raining in wolver den...I figured it would fit to have a weather article to discover the geography of Cradle. So if you can contribute, please do! I'm also looking for a picture of Haven during the Winterfest.
Cradle's surface is almsot always sunny (haven/rescue camp) with occasional rains (blades of the fallen mission)
Everything else is just artifical clockworks -biodomes with obvious controlled conditions- :S
I find this page stupid.
