Spartakus and the Sun Beneath the Sea

The group returns to Arkadia to attempt to free the Prisoners of Lost Time but discover that the Tehra will never be permanently restored until a riddle is solved and a second auracite is found.

The group is forced to battle in a real-life chess match against some of their most fearsome enemies.

Matt follows a devilish trickster and his supernatural pets, a giant eagle and a teleporting snake, on a dangerous quest to find "the gold at the earth's core", thinking it may be the second auracite. Spartakus, knowing that no one has ever returned from the journey, tries to stop him.

While crossing the deserts of Barkar, Spartakus recalls the incident that took away his family and forced him into slavery, his life as a gladiator, and the bitter reunion with his long-lost brother.

Ringnar holds Tehrig prisoner, forcing his triggies to build new luxury high-rise apartments for the pirates. When Nasty Max discovers what Ringnar is up to, the two begin a power struggle for the control of Tehrig, the tower, and the pirates' loyalties.

The travelers meet Tutankhaton, who is about to become pharaoh, and are caught up in a plot by the boy's uncle and the Priests of Amon, who want to seize power and return to worship of the old gods.

When the pirates capture just about everyone on the seas, the group find themselves prisoners in the hold of the pirates' ship. Meanwhile, Bic and Bac have to deal with being forced to work as Massmedia's musicians and trying to recover Spartakus' wristguard from the pirates' casino, all while trying to avoid nasty pickpockets.

The group befriends a city of people descended from the original Arkadians. They use their shapeshifting powers to help rescue Arkana from a pirate trap.

The travelers are aided in their search for an underground vein of metal that may be auracite by a powerful but suspicious magician called the Manitou. Along the way, they encounter a Cherokee from the surface who is looking for a new home for his people.

Guided by a mysterious mute woman, the group ascends a large tower filled with recorded knowledge from throughout history, but someone is trying to keep them from reaching the top.

The travelers are caught in the web of a giant spider. Bic and Bac are held captive by a tribe of their anteater cousins for their fire-making ability.

The group returns to Mira's village, which is preparing another confrontation with the Mogokhs. The villagers are divided over a plan to buy peace with the Mogokh leader by giving him a large ransom of gold. Spartakus helps with the plan, hoping he can learn something about his father from Baatu.

The travelers investigate the stratum where the People of the Deep mysteriously vanished long ago. To help Tehrig stay on course in this area, which has magnetic disturbances, they create a fake competitor to FIPIRATE, tricking the pirates into increasing their broadcast signal strength. Of course it also causes the pirates to put on a huge impromptu concert for all the rogues of the strata.

The group investigates a city closed in by giant walls and are captured by the army of Iron Men, who terrorize its citizens. With the help of an eccentric genius named Uncle Albert, they plot to help the people escape.
