Haha, you guys agree on it xD

And yup, personal plane costs 1 Might, any additional creatures you decide to create there will also cost Might.

XDDDDD of course we have a sun dammit!! Our big bang took care of that ;P
I was actually going to say, we don't have a moon. Moons can be created with Might though (imagine the mess we'll cause Undasis when there are 12 moons >:D)
