During the final push of the Dominion War, Captain Ian Quincy Knapp, commanding the USS Devonshire, encounters an unknown, powerful, and malevolent new force in the McAllister Nebula.

The mysteries of the Briar Patch beckon to the crew of the USS Excelsior, under the command of Captain Ian Quincy Knapp and his new senior staff. Their first mission has them looking for an foe that Knapp already has some knowledge of, but what they will discover will shock them all.

The Excelsior leads a task force after the Grey, but her crew quickly realizes they got more than what they bargained for!

The Independence is caught in 29th century intrigue when the crew discovers a legendary event in the past may have occurred due to tampering with the timeline.

Captain Knapp briefly clashes with new XO Elizabeth Shelby's attitude, before the Excelsior heads off to investigate the disappearance of the Nova-class USS Perihelion. Arriving at the ship's last known coordinates, they discover the ship in an impossibly close orbit of a quantum singularity, alongside an unknown vessel that dwarfs the Excelsior. But when an investigation reveals the strange, deleterious effects that the singularity had on the Perihelion crew and now the Excelsior crew as well, they realize what the ramifications could be for the entire galaxy.

The Grey are back, but the only one who can stop them may not be willing to help.
