With much of the federation trying to get back to business as usual after the near disaster that was frontier day 2401, USS Thyanis is drafted to ferry a team of engineers on a logistics mission to upgrade the Transporter equipment aboard some remote colonies and outposts.

For the first time since the Deneb Crisis, the crew has a chance to put the Thyanis back through her paces and try to get back to some old-fashioned science and exploration along the way.

But priorities change when the crew uncovers a more than 300-year-old mystery drifting through interstellar space. A secret; that may have wide-reaching implications for the Federation and ask the crew to pay a heavy price to uphold the principles of the Prime Directive.
