Premise
In a post-apocalyptic future, thousands of special operatives are tasked with preventing the collapse of society. These operatives, known as "travelers", have their consciousnesses sent back in time and transferred into the "host" body of present-day individuals who are about to die, minimizing unexpected impact on the future. The transfer requires the exact location of the target, made possible by 21st-century smartphones and GPS, providing time, elevation, latitude, and longitude (TELL) coordinates that are archived for use in the future. No transfer can be safely made to a time prior to one already performed.
Using social media and public records, travelers learn about their hosts, each maintaining the host's pre-existing life as cover for the rest of their lives. In teams of five, they carry out missions dictated by the Director, an artificial intelligence monitoring the timeline from the future. The goal of the missions is to save the planet from a series of catastrophic events. The Director can communicate with travelers through prepubescent children, who, unlike adults, can safely be animated by the Director for a short time without risking death.
Protocols
Travelers have several protocols to protect the timeline:
Protocol 1: The mission comes first.
Protocol 2: Leave the future in the past.
Protocol 3: Don't take a life, don't save a life, unless otherwise directed. Do not interfere.
Protocol 4: Do not reproduce.
Protocol 5: In the absence of direction, maintain your host's life.
Protocol 6: Do not communicate with other known travelers outside of your team unless sanctioned by the Director.
