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 Blackbird vibrated with a barely contained energy, its hull groaning as the graviton catapult’s containment fields locked into place around it. On the bridge, the air was thick with tension, the quiet only broken by the hum of power building in the ship’s systems, the clipped confirmations [...]

Gateway Station’s Arcade had once been the heart of the starbase, alive with visitors seeking entertainment. The Blackout had ended that, cutting off the steady flow of travellers to the Midgard system. Now, those stranded aboard drifted between bursts of restless energy and stretches of [...]

‘This is an unacceptable risk.’ With the mission looming, Rourke had every excuse to brush off Admiral Morgan. That hadn’t stopped the Midgard Sector Commander from inviting himself aboard Sirius and appearing in StratOps, the beating heart of squadron operations, just as they shifted to a [...]

‘Huh.’ That was the first response any of the assembled officers could gather as the last echoes of Cassidy’s briefing faded through the special operations unit lounge. Nallera was sprawled on one of the beanbags, the beef jerky she’d been chewing on as she’d come in now dangling out the [...]
