This is interesting. The climate timelines are still in the same place [say earth] or so right? A thought that came to mind when you said choice of good or destruction; using this to an advantage of exposure. When things are melted vs melting. If someone had to hide something for future self or other, they go and place it somewhere that would be completely covered in Wintoro. Only they would know it was there. Works in reverse too of course. 

This was just a thought that came to mind when I read that like I said. Very cool so far
