Veneks are a species of bloodthirsty barbarians seen in the Farscape episode "...Different Destinations." Their military is known as the "Venek Horde." Notable Veneks include General Grynes and Colonel Lennok.
500 years ago, the Veneks waged battle against the Peacekeepers over control of their planet's water supply. The Veneks attacked a Jocacean nurse monastery in order to gain access to the river. With the help of the compassionate General Grynes and Peacekeeper Dacon, a truce was signed and peace was made. About 100 years later, the Veneks abandoned the planet.
However, things change following the Moya crew's visit to the past. Instead of making peace, the Venek Horde slaughter the Jocacean nurses.
