USS Liberty is a Sagan-class light explorer commanded by Captain Elara Galcyon. Assigned to Sirius Squadron, her primary duty is deep space exploration beyond the Federation’s Beta Quadrant frontier. Based out of the squadron’s headquarters, Gateway Station, Liberty ventures into former Romulan Star Empire territory within the Midgard Sector and beyond. There, even missions close to home are shrouded in mystery and challenge, with Starfleet only now able to enter these vast swathes of space mere light-years from the border. Exploring the remnants of the fallen Empire, Liberty faces new challenges every day as she charts, surveys, and analyses the region. More often than not, she operates independently from her squadron, though can conduct reconnaissance operations, provide scientific evaluation, and offer tactical support should the formation be deployed in its entirety.

Sirius Expeditionary Squadron is a unit centered around the Odyssey-class USS Sirius under the command of Commodore Matt Rourke. Sirius Squadron stands ready to deploy outside or on the fringes of Federation territory at short notice to respond to emerging situations across the galaxy. With multiple versatile and powerful ships at its disposal, the squadron can operate independently and without support for extended periods, and is flexible enough to face a range of missions, including under volatile circumstances where objectives and conditions can quickly change. While this profile often leads Sirius Squadron to respond to geopolitical crises, the unit’s versatility make it equally suited emergent scientific investigations.
The main unit, organised around the Sirius herself, is an element of several powerful ships each able to take the lead or act independently depending on the mission’s needs. Deployed together, they are a supremely well-rounded and capable unit. Two additional divisions provide specialist support. The first, headed by the USS Redemption, acts as an operations element to provide engineering, humanitarian, or diplomatic services. The second, headed by the USS Liberty, fulfils dedicated exploratory or scientific missions. The divisions may deploy independently or in support of one another, depending on operational needs.

The skyline of Alpha Centauri City shimmered under the rising sun, gold light catching on glass towers and reconstructed skyways to gleam anew.

The Blackout was down. But the battle for Alpha Centauri wasn’t over. The bridge of the Endeavour was a storm barely held at bay. Emergency lights glowed hostile red across consoles, some of them cracked and sparking. Bulkheads groaned under strain. Officers moved with practiced urgency, the [...]

The lift ascended through the narrow shaft of emergency lights and vibrating metal. Beneath their feet, the pulsing hum of the outpost’s core reverberated through the station’s spine, a thudding heartbeat of engineering that made Rosewood’s teeth itch. Beside him, Ranicus checked her weapon [...]

Beyond the reinforced canopy of the Blackbird’s bridge, Underspace twisted and pulsed, a copper maelstrom of compressed subspace and rippling distortions. They had traded one form of chaos for another, the dazzling spectacle of starships ablaze in the name of Alpha Centauri swapped for this. That [...]
