Thanks for the kind words! Sort of in appendix-n / flash gordon fashion, the great wheel is just the golden lp that was sent out on voyager. It's implied that the daughters take it and use its auspicious landing to take control, but the disc itself has no inherent power (at least as written!)
But just like the vignettes and other parts of the adventure, you can add or remove whatever makes sense. Heck you could get rid of the wheel and replace it with a laser cannon!
