The Varro are a xenophobic humanoid species from the
Delta Quadrant. Their only known external difference from Humans being a
series of horizontal ridges down the back of their neck and along their spine.
In the 1970s, the Varro launched an ship of
exploration. As years went by, the ship became generational, and expanded.
Originally one segment, they built more and more, till the ship was much larger.
The Varro became a semi-oppressive regime and avoided contact with all other
cultures.
In 2375, the Varro ship had damage to the warp engines.
The U.S.S. Voyager came across the Varro ship. Parasites were eating
away the hulls of the ship. The sections that were affected were evacuated
and the ship's sections broke apart.
