Delphic Expanse scout
During the 2130s an unnamed Klingon starship attempted to enter the Delphic Expanse. However, when the ship eventually emerged from the Expanse it was discovered that its crew were still alive, but had became anatomically inverted. Following this incident, the Klingon High Council forbade any Klingon vessels from entering the Expanse. (ENT novelization: The Expanse).
