I felt like starting a discussion. Might do more of these if this goes well.
So, there's a theory that Shiver Star is actually Earth. Here's some stuff that may indicate they are the same planet:
|One Moon||One Moon|
|Continents||Continents shaped like those of Earth|
|Modern technology||Ruins of what once was modern technology|
So is it the same Earth as ours? Is it Earth in another dimension? Is it Earth in the future? If it is Earth, how did Earth become completely frozen? What do you think?
