Disrupt the Greengill Coast is part of the Shattered Sun Offensive Faction.

In this quest, seek out an NPC by the name of Captain Valindria, a female blood elf. She's located on a ship named Silvermoon's Pride. Note that she only appears after you've retaken the Sun's Reach Harbor.

Once you find her, she'll ask you to head over to the Greengill Coast in Sunwell Isle and free ten Greengill Slaves. Once this has been accomplished, travel back to Sun's Reach Harbor, board the Silvermoon's Pride and speak to Captain Valindria.

When you've done the deed and for your efforts you will receive 4 Gold/40 Silver, 7 Gold/59 Silver worth of experience and +250 reputation.
