“Protecting yesterday from tomorrow…”
After both the discovery of a viable means of time travel and, later, the Guardian of Forever by Captain James T. Kirk of the Starship Enterprise in 2260, the Federation Department of Temporal Investigations was formed. The organization, originally consisting of both civilian and Starfleet branches, was tasked with the enormous responsibility of monitoring, protecting and maintaining the timeline from changes by outside forces.

Stardate 108096.8 (Sun 27 Jun 2269): Researchers investigating historical records for clues to other temporal tampering come upon logs recorded by Captain Archer of the Starship Enterprise NX-01 that refer to the Temporal Cold War he learned of from the Suliban. Not long thereafter, one of the key players in the formation of DTI is revealed to be part of the TCW – a member of DTI himself who has traveled to the past to ensure the organization’s formation. His ship is suddenly destroyed when he attempts to travel to Gateway in an effort to use the Guardian to return to his own time, and no trace can be found of the attacker.

- The Rasmussen Effect (unwritten)
Stardate 206368.3 (Wed 4 Oct 2367): Berlinghoff Rasmussen, the twenty-second-century con man trapped two hundred fifty years in his future after a visit to the U.S.S. Enterprise NCC-1701-D, has left a mess in his wake that DTI agents Dulmer and Lucsly now have to clean up. Not only must they determine whether or not Rasmussen can be rehabilitated for life in the 24th century, they must also learn whether or not he would have had any impact on time had he stayed in his native era. And to make matters worse, they must find his time pod, as well as its original owner!
- Bozeman (unwritten)
Stardate 206695.8 (Thu 1 Feb 2368): DTI Assistant Director Harrington has been itching for a field assignment ever since he accepted his desk job. Finally, after making endless requests to his superiors, he’s got one, a mission so basic that it should have been given to a pair of rookies: help the crew of the U.S.S. Bozeman adapt to life in the 24th century. But there are some on this ship of 23rd century refugees who don’t want to sit idly by and adapt to the future. They have families and friends in the past, and they want to see them again. Now, it’s up to Harrington and Sekrinn to stop them from changing the past by preventing the Bozeman from coming to the future in the first place…
