What hides between Shadow and Light?

[dreadi]

I noticed that if you submit "fibonacci" you get a different message:


The moon casts a dark shadow upon the earth

Uh... No, I better not make another attempt until the light embraces me



dunno how that's supposed to work, though....

Nope. You can get that message with any random word.

This is one cryptic puzzle though. I can't seem to be getting anywhere with it. Too many seemingly unrelated parts to it.
