Epsilon Fleet is an independent Star Trek collaborative writing community where members create shared stories set in the 25th century. Its universe centers on two connected settings: the crew of the Sovereign-class USS Arawyn and the people rebuilding the fleet from Starbase 369. Writers can explore unfamiliar worlds, diplomacy, fragile alliances, buried histories, and the personal moments that unfold between missions.

Members create characters, write scenes with others, and help shape ongoing storylines through the Nova writing platform. The USS Arawyn setting follows Captain Sabrina Corbin and her crew, while Fleet Operations explores command, diplomacy, and the future of the wider fleet under Vice Admiral Sidra MacLaren. Newcomers can browse stories, meet the community on Discord, and apply to join; no knowledge of the full history is required.

Epsilon Fleet also offers podcast-style video recaps, Fleet Dispatches featuring news and developments, and a wiki covering characters, ships, locations, missions, and history. Its first year included more than 855,000 words and 11 completed missions and major story arcs.
