Grease Some Goblin Palm
Grease Some Goblin Palm is the name for the second part of both the merchants' and elven quests in Mayhew with identical objectives. Since the player must chose to work for either the Elves or the merchants and not both, only one of two variants will be accessible.
Elven Quest Summary and Walkthrough
To be able to accept his quest, you must have already recovered the chest stolen from the Merchants in favor of the merchants, as done with the completion of the quest Pillage the Caravan.
After returning to the bungalow, Quellyn informs you that you must now take the chest to a certain goblin in the Goblin Ghetto. Specifically, you must take the chest to the goblin rebel, who after a brief exchange of dialog, will return the favor by giving you 500 gold.
Proceed to the Next Quest: You may now return to the Elven bungalow for the next mission from Quellyn: Grease That Palm Again.
Merchants Quest Summary and Walkthrough
To be able to accept his quest, you must have obtained the chest for the merchants, either by defending the warehouse against elven raiders (Protect the Warehouse Quest) or recovering it back from the raiders (Get the Loot! quest).
Returing to the headquarters with the chest, the merchant manager will tell you to give the chest to a certain goblin. He says that "There's a group of them unhappy with current leadership and we're sponsoring them a little bit." As in the elven version, the goblin to seek is the goblin rebel in the Goblin Ghetto. After a brief conversation, the rebel will accept the chest in exchange for 500 gold.
Proceed to the Next Quest: You may now return to the headquarters for the next mission: Wine-ing Elves.
