Can someone "explain" what the fifthist church is?

Here you go.

Check out the Groups Of Interest page for some of the other's you'll see around a lot.

It's a multifaceted group of astrological star cultists manifesting in different parts of the globe in the form of celebrity fraternities, rock bands, churches, etc.. Occasionally they're anomalous, but mostly they just worship a vague goal of physical and psychological cosmic transcendence. They're probably one of the hardest groups to really get a concrete handle on, so don't fret if you're still completely lost after looking over some of their stuff. That's what makes them fun and creepy.

What are its goals?

For me, the theme of fifthism is religiousity without any core coherent human theology. The trappings are familiar, but the center is something alien.
