188. INT. ROCK LEDGE - HALL OF RITES - SIETCH TABR - NIGHT

...

Stilgar motions to Paul.

STILGAR
(whispering to Paul)
Do you know the Water of Life?... Come...
...Watch... the mystery of mysteries... the
end and the beginning.

He shows Paul through a narrow passageway -- almost a slot through the stone to a small room. Through an opening in the stone wall, Paul is shown a very strange and somewhat horrifying scene.


189. INT. BABY WORM - MAKER ROOM - SIETCH TABR - NIGHT

A thirty-foot baby worm is being lowered into a stone chamber. The chamber is then covered with a wire top. Valves are turned and water rushes into the chamber. The worm begins to writhe violently and SMOKE pours from it. The worm dissolves partially and suddenly, before it dies, it secretes a dark blue bile out its mouth. It spasms and dies.

189A. INT. MAKER ROOM - SIETCH TABR - NIGHT

The bile and worm water are combined into ceremonial containers. Paul turns to Stilgar.

STILGAR
The Water of Life.

PAUL
(inner voice)
The most lethal poison in the Universe.
