Some of the covers:
But the comics are far more complex(as usual)
There you find for example the double figure male/female of the Emperor that was meant to be in his Dune scenario.

The wiki page is pretty scarce:

I remember reading them as a kid, and just like Dune you know there is hidden meanings and symbolism you'll understand later, making it an endless source of knowledge and pleasure.
nb: the us edition in was censored
