As the title of this novel suggests, the enigmatic “Preservers” are at the heart of the story. The implication in Preserver is that this species is responsible for galaxy-changing events and interference spanning billions of years. They may even be the same race of ancient humanoids seen in the TNG episode “The Chase,” responsible for “seeding” worlds throughout our galaxy and giving rise to the humanoid form that is so common in the Star Trek universe. However, the only canon reference to the Preservers comes to us from the TOS episode “The Paradise Syndrome,” in which it is revealed that they were responsible for transplanting a community of Native Americans from Earth to another planet. Seeing as this would have to have occurred within the last 10,000 years, I always find it strange that the Preservers are linked to events that span billions of years. Preserver isn’t the only story to do this; other sources such as Star Trek Online have also postulated an ancient origin for the Preservers.
