Potential Targets for colonization

by **Spooky_Zalost** Sat Aug 18, 2012 11:49 pm

this is just a list really of potential targets that we could attempt to colonize and more than likely terraform so please add to the list if you think I missed any, and please only REAL places, Alderan and Vulcan don't count. this list will be updated on an ongoing basis and I will try to do my best to be accurate updating information as needed.

Conclusion: already colonized but could be re-terraformed to undo the damaged we have done to the climate which is making it harder to live on.
