Once you turn this quest in to Gloin, the chain continues with "Rumours of the North" (48) a mission that sends you back into Goblin Town to search for orders on Uruk Orcs.
However, turning in this quest also opens up a new, seperate line of quests from the dwarf Vighar Roadwalker, who is at Gloin's Camp. After turning in "Memory of the Wargs" two new quests are available from him:
-"Drum Keepers" (50) (Small Fellowship) - Defeat Kaushar - Defeat goblin lash-masters 0/8
-"Leaders of the Deep" (50) - Find and kill Zagh Master of the Guard, Find and kill Farmak the Best Runner, Find and kill Dagal the Observer
