CWBP 2 : Determining the genre and era

[Ghostman]

I took a look at Ganymede and Titan, the two biggest satellites in our system to get an idea. They take about 7 to 16 days to orbit while the Moon takes 28 days. They are all tide locked. That mean that if your are on the tide locked side, you have nearly half of that time without light.

That can't be correct. The time without light would last only for as long as the moon remains in the shadow of it's mother planet. That certainly does NOT mean anywhere near half the period of it's orbit. The span of time depends on the moon's distance to the planet, as well as the diameter of the planet.

EDIT: Ok, now I see what you meant - the time the side facing the planet is facing away from the star. This actually applies to every location on the moon (save it's poles) equally, not just the tide locked side. That said, my second point (below) may still complicate things, depending on the angle...

What's more, you appear to be assuming that the plane of the moon's orbit around the planet is the same as the plane of the planet's orbit around the star. If these planes are tilted relative each other at a significant angle, the moon won't actually enter the planet's shadow at all for much of the year.
