Summary
Blurb
Experience time travel and engage Tzenkethi raiders!

"Captain's Log: We have been ordered to suspend our routine patrol of the Tzenkethi border and proceed to the nearby Federation colony Natsumi's World, where we will take aboard two agents of the Federation Department of Temporal Investigations. As usual, the DTI has provided no details, stating merely that we are to place ourselves at the disposal of the agents and follow their instructions. Thus, I have no idea whether to prepare my crew to face some unimaginable existential threat or, far more likely with the DTI, days of tedious routine and bureaucratic obstruction."

When the player characters receive an assignment from the DTI to deliver a powerful alien artifact to DTI facilities, they are soon set upon by Tzenkethi raiders. The ensuing skirmish destabilizes the artifact's energy field, and the characters discover that they have somehow changed into alternate timeline versions of themselves! Can the characters deal with the sudden changes in themselves and the rest of the crew, and also figure out how to get back to their own time, all the while battling the Tzenkethi?
