USS Vortex

From Memory Alpha, the free Star Trek reference.

The USS Vortex is an imaginary starship in The Doctor's holonovel Photons Be Free that is much darker compared to USS Voyager and is always at red alert, populated by a distorted version of the Voyager crew, whose traits (particularly their negative ones) were exaggerated. It is commanded by an imaginary war-like captain called Captain Jenkins. The participant in Photons Be Free worked on the Vortex as an Emergency Medical Hologram. (VOY: "Author, Author")
