Lux Tenebras: Decyphered

[RockWorm]

Where did this cipher text come from?
The only one I can find about Lux Tenebras is this one:

YNGPPUZFVKJZIDSTCWIZVYIDFYVQOPSBAVJUIUNJVPLIFRMHMZQDFABMNWMMLRYSWAQAZRSXQEDMJWHSG
VJBSFJVTCSVVCPFIMGMUNSOCOQGRRJUCAVIS

Which there is no soulution to yet, right?

I am trying to break it now, but haven't made much progress.

By using some simple scripts, I have decided that it must be shuffled some way; there is not one combination of thress successive letters that is repeated (which means that the text wouldn't contain "the", "and", "for", "are", or any other of the most used three letter words more than once, and I find that hard to believe). Therefore, it must be shuffled!

Any other leads?

nope,but I hope you are getting somewhere with this
