Clouds

Floating high up above in the air there are tiny droplets of water molecules all kind of mushed together.

They form these things that humans call "Clouds",

But ours are oh-so different, they are our main power source.

These Clouds can take us to many places past, present and future, and they power our various devices on many different levels. The bigger the cloud is, the more you can do with it, but cloud density and how low to the ground they are also plays a huge roll in their abilities. When the clouds are closer to the ground they are easier to enter, but if they get too low and become fog, things can get kind of crazy...
