Free the Nurgan Slaves(Normal):
In the Mines of Nurga, there are slaves of various races who wish to be set free. Each slave asks for 3 items: a small iron shackle key, a pouch of supplies, and a strong restorative. The small iron shackle key drops from Overseer Pruckib, the pouch of supplies drops from Taskmaster Yajo, and the strong restorative drops from Slave Driver Nimol.
Once you've handed in the items, 6 waves of 5 goblins spawn. At the end, a named will spawn (Mine Overseer Narrik). When he is killed, the slave escapes and flees to his home where he gives another quest.
A different slave will spawn to take the freed slave's place.
