Tulaturs

Tulaturs are a fictional species that appear in the science fiction novel "The Expanse" series by James S.A. Corey. Within the narrative, they are a highly intelligent and technologically advanced alien race, though their presence is largely enigmatic and their physical form is not explicitly detailed in the books. They are known for their advanced understanding of physics and their ability to manipulate protomolecule technology. The protomolecule itself is a mysterious alien artifact that serves as a central plot device, capable of transforming biological matter and creating complex structures. Tulaturs are believed to have created the protomolecule or at least be its original custodians. Their motivations and ultimate goals remain largely unknown to the human characters, contributing to their mystique. The characters in "The Expanse" often refer to them as "The Builders" due to their apparent role in constructing the protomolecule gates that allow for rapid interstellar travel. Their history and civilization are hinted at through the remnants of their technology found scattered throughout the solar system. The discovery of protomolecule sites and the subsequent emergence of new technologies are key plot points driven by the enigmatic influence of the Tulaturs.
