Prison deck coupling

The Prison Deck Coupling was a Terran Dominion structure located on the prison ship Moros. In 2505, Commander Jim Raynor, upon being captured at the Umojan Research Station EB-103 facility, was taken to the prison ship. Later, after learning the whereabouts of the Moros's location, Sarah Kerrigan and her zerg forces boarded the ship in order rescue him. After a substantial number of Dominion defenses were breached, a Dominion officer ordered the coupling be destroyed, but the zerg prevented it, allowing Kerrigan to penetrate down to the prison deck.
