USS Endeavour
Constitution III-class • NCC-91895 • Endeavour Explorer Division • Sirius Expeditionary Squadron • Fourth Fleet • Managed by ADM Alexander Beckett
The arching sky is calling
Spacemen back to their trade.
ALL HANDS! STAND BY! FREE FALLING!
And the lights below us fade.
Out ride the sons of Terra,
Far drives the thundering jet,
Up leaps a race of Earthmen,
Out, far, and onward yet.
– ‘The Green Hills of Earth,’ Robert Heinlein
The USS Endeavour (NCC-91895) is a Constitution III-class starship assigned to the Fourth Fleet under the command of Karana Valance. Commissioned in early 2400, Endeavour was built from the parts of her decommissioned namesake, a Manticore-class, and reformed into something new: a symbol of Starfleet’s spirit of cooperation and exploration.
Since early 2401, she has been assigned to the Midgard Sector, on the Beta Quadrant border, and is part of Sirius Squadron, a unit responsible for maintaining the Federation’s regional interests. These interests include diplomatic outreach, with a particular focus on cooperation with the Federation’s allies in the Romulan Republic, as well as humanitarian aid for former Star Empire worlds, exploration of the vast and unknown territories of the fallen empire, and supporting the Federation’s border holdings and needs. As a powerful ship with a multi-mission profile, Endeavour’s day-to-day consists of providing necessary support to these essential operations.
Endeavour’s primary duty, however, is to act as the squadron’s expeditionary unit, the first choice to respond to emerging situations within the Midgard Sector and beyond. These duties may include humanitarian or tactical crises, but also extend to scientific mysteries or entering diplomatic hot-spots. When necessary, Endeavour can act independently for extended periods, and thus may be dispatched to regions or for durations where immediate support may be unavailable for some time.
Either duty keeps Endeavour’s crew occupied and challenged. In Midgard, Endeavour now seeks to reach out to those abandoned by the collapse of the empire, forge new friendships, and explore this newly-independent expanse. Refugees need Starfleet aid, worlds no longer under the rule of Rator or Romulus need welcoming to the galactic family, and vast stretches of the unknown must be explored. But the region is still volatile and dangerous, a breeding ground for criminals and warlords. Not everyone will look fondly on the Federation’s arrival, and many will have a right to be left alone. Walking the line between reaching out and interfering, between exploring and trespassing, between helping and imposing, is a tall challenge for Endeavour in this new era of Starfleet’s efforts to reach back out to the galaxy, and bring hope to a shrouded region.

BF: Endeavour began in late 2019, and is over 25 missions and almost a million words long. While it is written with the hope of being accessible to new readers, some character threads and storylines are several years old. The following is a suggested reading list for people who want to catch up on old storylines, but do not necessarily wish to read all of Endeavour up to this point. An overall narrative summary can be found here and here on the wiki.
The suggested missions, in order:
- 8: The Widening Gyre (highly recommended for introducing the setting of Teros, and key developments for the characters Kharth, Airex, and Beckett)
- 9: Things Fall Apart – part of Fleet Action 2021: Echoes of the Tkon (highly recommended for introducing the setting of Teros, and key developments for the characters Rourke, Kharth, and Airex)
- 10: The Blood-Dimmed Tide – part of Fleet Action 2021: Echoes of the Tkon (low recommendation; continues FA storyline)
- 11: Slouching Towards Bethlehem – part of Fleet Action 2021: Echoes of the Tkon (low recommendation; concludes the FA storyline)
- 15: A Handful of Dust – part of Campaign 1 2022: Stormbreaker (recommended; key developments for the characters Valance, Cortez, Airex, Kharth, Beckett, and Thawn)
- 16: Certain Dark Things (recommended; key developments for the characters Valance, Airex, Kharth)
- 20: All the Devils Are Here – part of Campaign 2 2022: Blood Dilithium (recommended)
- 24: Wherever You Roam (highly recommended; introduces the Midgard Sector setting)
Sirius Expeditionary Squadron
Sirius Expeditionary Squadron is a unit centered around the Odyssey-class USS Sirius under the command of Commodore Matt Rourke and oversight of Director of Squadron Operations Vice Admiral Owen Morgan. Sirius Squadron stands ready to deploy outside or at 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 squadron is based out of Gateway Station, in the Midgard Sector, which provides logistical support and operational and administrative leadership.
The HQ unit is organised around the Sirius herself, supported by her attached ship Alhabor. Four additional divisions provide specialist support:
- Endeavour Division: An administrative group including allied Romulan Republic and Klingon Empire assets assigned to the Fourth Fleet. The division exists to maintain unified oversight and communication, each ship answering directly to squadron command, rather than deploying as a task group.
- Liberty Science and Exploration Division: Conducts exploratory operations primarily beyond the Federation’s borders, expanding Starfleet’s understanding of unknown regions. When deployed alongside the squadron, these ships provide support through reconnaissance and advance operations.
- Memphis Division: Advances the squadron’s knowledge through sustained research, survey missions, and integrated intelligence work. Specialises in follow-up study and the detailed analysis of squadron-priority regions, organisations, or phenomena.
- Tannhäuser Operations and Outreach Division: Provides engineering, humanitarian, or diplomatic services primarily on the Federation frontier. This division is the most likely to be deployed as a unit and can be sent to whole regions in need, giving disaster relief or building infrastructure. When deployed alongside the squadron, these ships provide logistical support.
The divisions may deploy independently or in support of one another, depending on operational needs.
