Delphic Expanse

The Delphic Expanse was an area of space located in the Alpha Quadrant, approximately 50 light years from the Sol system. While its exact dimensions remain unknown, during the 22nd century Vulcan scientists estimated it to be around 2,000 light years across.

Entering the Expanse during the 22nd century proved hazardous to shipping as it was surrounded by thermobaric clouds and various subspace anomalies inside the Expanse. Shipping also avoided the Delphic Expanse after hearing about strange happenings occuring to ships and crews that entered. During the 2130s, a Klingon vessel emerged from the Expanse and it was discovered that its crew had been anatomically inverted, yet they still lived. Following this incident the Klingon High Council forbade all vessels from entering. (ENT novelization: The Expanse).

In late 2152, the Vulcan vessel Seleya was drawn into the Expanse and all contact was lost. The Vulcan's dispatched the Vaankara to investigate, but contact was also lost with this vessel. It was later discovered that the crew had gone insane within two days of entering the Expanse. (ENT novelization: The Expanse and episode: "Impulse").
