In a coarse whispering voice the oracle intones...
And with that, the crystal ball flashs a brilliant white, blinding you momentarily. And you hear with out hearing, a voice from some distant dimension...
``From past, present and future,''
``From distant dimensions as yet unseen,''
``From books, lost in time or as yet unwritten,''
``A message comes with the light for thee... ''
"Seshmarl, to know the future is to change it, so that it wriggles like a many-headed snake. What you see is false, because you've seen it." -- Larry Niven, "The Burning City"
When your vision returns the oracle has returned to the way she was before.
You can return to the ante-chamber or throw another silver zorkmid onto the oracle's table.
