Since the dwarf-expedition entered Moria, there have been far too many encounters with goblins.
'Well, ${PLAYER}, we have been lucky so far in that the goblins infesting Khazad-dûm seem to be terribly disorganized, with inept leaders.
'Nevertheless, we cannot relax our guard. If I read things rightly, there is one particular leader among the nearby goblin-tribe who has been bold enough to organize a raid against the Deep Descent, and I think it would be best if he doesn't live long enough to carry out his ploy.
'See if you cannot perhaps weaken the goblin-forces in Gamil Filik, and deal with their chieftain while you are at it.'
Gathrok and his goblins are in Gamil Filik, south-east of the Deep Descent.
Stíling has asked you to defeat Gathrok, a goblin-chieftain, and weaken his forces.
Stíling is hiding just at the outskirts of Gamil Filik in the Silvertine Lodes.
You should return to Stíling and tell him that you were able to defeat Gathrok.
