Typhon Expanse
From Star Trek : Freedom's Wiki
The Typhon Expanse is a region of space with unusual temporal properties. Located in the Beta Quadrant outside of the Romulan Star Empire in the coreward section, this expanse of space is known to have strange temporal qualities in some areas. In 2370 the Expanse and the space around it was still largely unexplored. No further exploration has taken place since the beginning of the Civil War. The USS Champlain captained by Edward Wolfe was recently dispatched to chart that area of space and patrol for evidence of Doenitz's forces.
