Deep Space 4

A self-sustaining station in the confused frontier area between Romulus and Vulcan, Deep Space 4 saw all kinds pass through it, from mad archaeologists to pirates to naiive astrophysicists. Technically a Starfleet command post, its security force despaired of ever getting rid of all the Tal Shiar agents on board. Hence, it served as an informal diplomatic point, intelligence-gathering hub, and underground marketplace.^[2]

In 2369, Captain Picard‘s old archaeology professor, Richard Galen, hoped to board an Al-Leyan transport ship to Caere at Deep Space 4 in order to continue his pursuit of knowledge about the first humanoids to live in the Milky Way Galaxy.^[1]
