USS Sirius is an Odyssey-class heavy explorer and the flagship of Sirius Squadron, under the command of Commodore Matt Rourke. With her size and self-sufficiency, Sirius is the main hub of all formation operations, able to support and supply other starships and their crews for an extended duration. When operating in the Midgard Sector, Sirius serves as a forward command post for missions across the region, or is directly responsible for humanitarian, scientific, or strategic duties requiring her vast resources. Whether at the heart of a deployment of the whole squadron or taking primary responsibility for a specific operation, the assigning of the USS Sirius to a mission demonstrates command takes a matter deeply seriously.

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.

USS Endeavour and USS Sirius
The beach was a riot of light and sound. Fat rays of the golden afternoon sun skipped across rolling waves and onto the vast expanse of white sand, where laughter and conversation hummed to and beyond the water’s edge. Parasols dotted the beach and promenade like bright, haphazardly planted [...]

The low sun turned the waves to gold as it stretched across the beachfront market. Lanterns flickered over stalls of fabrics, artisan jewellery, wood-carved figures. Somewhere, a busker strummed a jaunty tune, light and sharp above the hum of the crowd. Valance thought it was kitschy and annoying, [...]

‘See? You didn’t hate it.’ ‘It’s not about liking or disliking it,’ Rosara Thawn said primly as they crossed the path through the sun-soaked gardens. ‘It’s about not seeing the point of it all.’ Elsa Lindgren’s smile twisted as she popped her sunglasses down from her forehead. [...]
