After witnessing the execution of five of Skorbo's accomplices, and the
banishment of one of them who refuses to submit, Niall discovers the whereabouts of
Skorbo's "larder," where his paralyzed victims are hung like carcasses in a butcher's
shop, awaiting their turn to be eaten. One of these is a girl, Charis, whose pale skin
indicates that she is also from the underground realm of the Magician. Recognizing
that Charis is his last clue to the whereabouts of the Magician, Niall decides to keep
her in his palace until she can be restored to consciousness.
In the house that had been occupied by Skorbo's killers, Niall finds froglike
talismans carved from green stone, and realizes that they emanate a malevolent force.
A mat of some kind of seaweed proves to be the means by which the assassins were
able to draw vital energy from the girl who accompanied them.
Niall learns that Skorbo had once been lost in the mountains to the north of the
Great Wall, after a crash landing in his spider balloon. Niall begins to entertain the
suspicion that there may have been some connection between Skorbo and the
Magician, and that Skorbo's death may have been in revenge for some kind of
treachery.
Niall's attempt to learn more about the Great Wall, and the Gray Mountains, is
frustrated by the fact that the spiders are almost totally ignorant of their own history.
Then he learns that the greatest of all spider warriors, Cheb the Mighty, is kept in a
state of suspended animation by the vital energy of young spiders, and that Niall, as
the ruler of the spider city, will be allowed to question Cheb.
A journey beneath the city leads him to the sacred cave; there young acolytes
bring back the great spider warrior from the land of the dead. Cheb describes how the
spiders first learned to make use of human servants, who regarded themselves as
spiders rather than human beings, and how these psychological hybrids helped Cheb
to enslave all the remaining humans. Niall then speaks with the spirit of Cheb's
famous adviser, Qisib the Wise, and learns of the events that led to the building of the
Great Wall.
Qisib tells of how Cheb's successor sent his human servant Madig to select a
site for a new city in the Gray Mountains of the north. Madig, alone of all his party,
returned with a message for the Spider Lord that the Gray Mountains were the
territory of the Magician, who would destroy any invaders.
The Spider Lord was incensed -- particularly when Madig died, apparently of
a slow poison that had been administered by the Magician. An immense army of
spiders and human foot soldiers marched north, but were destroyed by a gale and a
flood in the deep valley known as the Valley of the Great Lake. The Spider Lord and
his councilor Qisib alone survived. After this catastrophe Qisib supervised the
building of a Great Wall in what is now known as the Valley of the Dead.
Niall has no doubt that the storm was caused by the powers of the Magician.
Qisib recounts Madig's own story of how his party was overwhelmed in the
dark, blindfolded, and taken to some strange city, where the streets are silent and
nobody speaks above a whisper. There, still blindfolded, Madig was ordered to carry
a message to the Spider Lord, threatening him with destruction if he ventured into the
Gray Mountains. Madig was told that if he did not return within thirty days, he would
die and the other prisoners would suffer horrible deaths. Madig, of course, did not
return, and died -- as the Magician foretold -- after thirty days.
When Niall returns from the sacred cave to his palace, he learns that his
brother Veig, who has cut himself on the ax used to kill Skorbo, is dangerously ill.
Grel, a young spider, detects the presence of some evil force in the palace. Niall
tracks it down to his bedroom, where he has left one of the toadlike figurines that he
found in the house of the assassins.
