Space, as it goes, is often considered the final frontier, but anyone who's served aboard a Starfleet vessel can tell you that sometimes time likes to stick it's foot in and mix things up a bit. When artifacts and unusual sensor readings are brought to the attention of the Admiralty, Celestia and Angella decide to gather their best and most trusted people to investigate.

• Captain Sunset Royal, an expat from the so-called 'mirror' universe and Admiral Celestia's chosen inheritor of her former ship, the USS Harmony
• Captain Adora Gray, Angella's choice to lead the strike team, captain of the USS Sword of Protection
• Captain Ranma Saotome, considered a wildcard in the fleet but known for pulling her crew out of insane disasters, captain of the USS Invincible

These three and others will find themselves on a journey that will reveal that the universe they think they know is falling apart at the seams, and they may be the only ones who can keep it from unraveling into oblivion.
