The Bonaventure (10281NCC) was, according to Montgomery Scott, the first starship to have warp drive installed. The exterior design was reminiscent to that of a precursor to the Constitution-class. Sometime prior to the 2260s, the Bonaventure, and all hands, vanished without a trace on her third voyage, in what was later determined to be the Delta Triangle. The ship encountered a time warp vortex and became trapped inside Elysia, a small alternate universe, a parallel time continuum, that periodically touched the prime universe in the Delta Triangle region. In Elysia, the Bonaventure remained adrift along with a large number of other ships unable to escape.
