Synopsis for "The Reality War"
Dr. Strange and Clea have decided to take a vacation and take a flight to Rome. During the flight, Clea has a dream about Sibylla, the founder of an ancient Roman group known as the Sibyls. Sibylla explains how she was chosen by Apollo to act as a prophet to the people. After living out her mortal life in the temple of Apollo and Artemis (the Nexus of all realities), Apollo allowed her spirit to endure and they would watch as each of her descendants would take on the role of a Sibyl. However, one descendant, named Thaleia, went mad and her behavior thereafter lead to the loss of faith in the Sibyline Sisterhood. Thaleia would ultimately poison herself.
When the prophecy of the "Black Oracle" came to be, another Sibylla would be needed to save the world from danger. The dream Clea is having is a summons that she is the next to be part of the sisterhood.
When Stephen and Clea arrive in Rome, they are shocked to see almost immaterial Roman soldiers bearing laser rifles. Deciding to investigate, the two travel to the Temple of Apollo and Artemis. There they witness more reality warps, as well as meet Sibylla. She explains that their reality will be invaded from beings from an alternate reality, led by the evil wizard Xennus who comes from a reality where the Roman empire never fell and society became even more advanced than their native dimension.
Clea agrees to be the third link, working in unison with Sibylla and the spirit of Thaleia to seal the rift in reality. Dr. Strange's task is to prevent Xennus from stopping the women. He battles his foe throughout various dimensions. Finally, the evil wizard fails in his goal and the three women manage to banish him back to his own dimension. With their mission a success, Sibylla's body crumbles to dust and the cavern caves in, leaving Strange and Clea alone to witness a beautiful sunrise.
