USS Endeavour (parallel universe)

Multiple realities
(covers information from several alternate timelines)

The USS Endeavour was an Intrepid-class Federation starship operated by Starfleet in a parallel universe during the late 24th century.

In 2382, the Endeavour, under the command of Captain Tersal, was pulled through a quantum fissure into the prime universe. As the prime universe had a much larger scale than their native one, the Endeavour was now the size of an amoeba. The stranded Endeavour crew endured "a month of hell" attempting to gather energy and materials to construct a dimensional gate, which manifested to outside observers as a destructive nanite cluster on the cruise ship Cosmic Duchess.

After a USS Cerritos away team neutralized the nanites and made contact with the Endeavour, Admiral Milius promised to aid them in returning to their home dimension. (LD: "The Best Exotic Nanite Hotel")
