Exact Dialogue:
I can see what you see not.
Vision milky then eyes rot.
When you turn they will be gone,
whispering their hidden song.
Then you see what cannot be,
shadows move where light should be.
Out of darkness, out of mind,
cast down into the Halls of the Blind.

Details: Explore the remainder of this level of the Catacombs until you eventually find a section that does not appear to have any doors. Check your automap to find that two areas in the wall are actually illusions and you can step right through them. You'll have to slay quite a few invisible demons in this area, but you'll find a unique piece of jewelry, the Optic Amulet, on the floor inside.
