Remote Mining Station Four (or Forsaken Station) was a mining station on Moria owned by the Kel-Morian Combine. It was surrounded by a vast dune sea, with some mountainous terrain far in the distance. It was unusually militarized, as if protecting something important.
During the Second Great War, the outpost came under attack by protoss forces, seeking whatever the base had housed. Kel-Morian forces, under the command of Lieutenant Colonel Gwen Maxwell mounted a defense, and managed to push back the protoss with a line of marauders and firebats, as well as a well placed nuclear missile called down by a ghost. This caused radiation levels around the outpost to become unsafe.
In the conflict, three colossi was deployed, which incinerated many of the terran defenders. Two were destroyed by vikings, but survived, damaged but able to fall back. Captain Marius Blackwood broke formation to peruse it, eventually chasing it down and destroying it with two shots from his siege tank. However, the protoss regrouped and pushed out to kill Blackwood. A medivac dropship was sent, which evacuated Blackwood just in time, but was shot down by a phoenix, killing both the pilot and Blackwood.
