A planet orbited by Surplus Depot Zed-15, the Federation ship graveyard managed by the Zakdorn, where the Enterprise-D traced stolen Vulcan ship parts in Unification.
Qualor II is the location of Surplus Depot Zed-15, a vast field of decommissioned starships administered by the fussy Zakdorn quartermaster Klim Dokachin. It appears in both parts of Unification (2368).
Riker brings the Enterprise-D there after wreckage of a Ferengi cargo ship is found to contain pieces of the Vulcan vessel T'Pau. Dokachin, won over by Troi's tact, discovers that the T'Pau is missing from its berth and that an unidentified ship has been collecting stores meant for another vessel. That ship opens fire and is destroyed.
Riker later returns to a bar at Qualor II, where the four-armed musician Amarie points him to the Ferengi arms dealer Omag. The trail leads to a Romulan plot to invade Vulcan.
