“Ranna," she said aloud, touching the first, the smallest bell. Ranna the sleepbringer, the sweet, low sound that brought silence in its wake.

"Mosrael." The second bell, a harsh, rowdy bell. Mosrael was the waker, the bell Sabriel should never use, the bell whose sound was a seesaw, throwing the ringer further into Death, as it brought the listener into Life.
"Kibeth." Kibeth, the walker. A bell of several sounds, a difficult and contrary bell. It could give freedom of movement to one of the Dead, or walk them through the next gate. Many a necromancer had stumbled with Kibeth and walked where they would not.
"Dyrim." A musical bell, of clear and pretty tone. Dyrim was the voice that the Dead so often lost. But Dyrim could also still a tongue that moved too freely.
"Belgaer." Another tricksome bell, that sought to ring of its own accord. Belgaer was the thinking bell, the bell most necromancers scorned to use. It could restore independent thought, memory and all the patterns of a living person. Or, slipping in a careless hand, erase them.
"Saraneth." The deepest, lowest bell. The sound of strength. Saraneth was the binder, the bell that shackled the Dead to the wielder's will. And last, the largest bell, the one Sabriel's cold fingers found colder still, even in the leather case that kept it silent.
"Astarael, the Sorrowful," whispered Sabriel. Astarael was the banisher, the final bell. Properly rung, it cast everyone who heard it far into Death. Everyone, including the ringer.”
