With the Worlds and Planets folio slowly growing, I thought about throwing a little inspirational resource at you.Terraforming
is to be a collection of various ideas bound to this concept. I prefer to not go too heavily into science, it is better to explain topics lightly and provide a link. (Please excuse the broken external links... it can't be helped for now.)
In addition to the major themes, there can be any number of short ideas, that can inspire interesting or unusual worlds, or plot hooks related to them.
I have put a few down so far... now I would like to ask you to help me with all the great options I have forgotten and you have in mind. And if you find something that you like, steal away!
