Okay I’m going to draw a comic about this later but like,
Just imagine Zant seeing stars for the first time. I doubt that the twilight realm has stars in the same way that the light realm does, especially since their ‘sun’ is basically two orbs that can be picked up and carried around and won’t burn you at all. Really, all the sky has there are those little black floaties and clouds.
And the first time he sees stars he just completely flabbergasted like, “Ghirahim, why is the sky glistening!?” So Ghirahim explains what they are to him and from then on they have the hardest time getting Zant to do anything at night because he won’t stop looking at the sky.
Basically he just loves the night sky, and wants to know everything about it. I don’t think Ganondorf would have the patience to put up with it all the time, but I like to think that Ghirahim would humor him and star gaze with him when they had free-time.
