This quest is given by Janitor Zolbuk near the entrance of Runnyeye if you speak the goblin tongue and are level 33+. You can learn goblin by completing the Claiming the Goblish Tongue quest (see related quests).
Zolbuk will ask you to kill 12 goblins in Runnyeye. Any will do. After killing them return to him for a nice chunk of coin and experience.
This will also open up the Runnyeye Filth quest.
