When the Shannon family first gets to Terra Nova, they meet Commander Nathaniel Taylor. He is the first person to go to Terra Nova and leader of the settlement. Taylor warns the travelers that while Terra Nova is a place of new opportunities and fresh beginnings, all is not as idyllic as it looks. Along with blue skies, large waterfalls and vegetation, the land is full of danger. This danger is not just from the man-eating dinosaurs. There is also a second group of people lead by Mira, who is opposed to Taylor and his leadership. This group, the Sixers, came to Terra Nova on the Sixth Pilgrimage. Many of the people on that pilgrimage had secret reasons for being there.
