The Fantastic Journey

Varian, under the influence of a love drug, meets a woman named Gwenith from a religious community in a geologically unstable zone. When the others arrive Varian reveals he's about to get married. They soon discover that the community fanatically worships a volcano god called Vatticus, who demands human sacrifices.

An alien dictator, Tarant, is planning to invade other time zones and conquer the island. Willoway pretends to agree with him so that he can learn Tarant's secrets. Meanwhile, Liana takes pity on an abused furry creature called the Nefring.

The travelers arrive in a new zone with Greek ruins and meet a young boy who has escaped from a community inhabited solely by children led by the bullying teenager Alpha.

The travelers are separated by a red cloud which leaves Liana as the 'guest' of Jonathan Willoway, who is the master of a utopian community of golden-garbed androids, and the others trapped in a dark swamp surrounded by green-skinned humanoids. Willoway tries to convince Liana to marry him while Fred's medical skills prove invaluable in discovering the truth.

With many of the original party returned to their own time, Varian, Scott and Fred find themselves caught up in the machinations of a being called The Source, which has enslaved the inhabitants of the city of Atlantium, built by the survivors of the original Atlantis. The Source plans to us Scott's life force to regenerate itself. The trio are aided by Liana, who reveals that she is half alien.

A group of scientists sailing the Caribbean are shipwrecked after entering a strange green mist in the Bermuda Triangle. They do not know the island they are stranded on but it seems past, present and future co-exist. After meeting 23rd century healer Varian and encountering 16th century privateers, the survivors begin their quest to return to their own time.
