Information received from the letters you recovered in Black Speech led Glóin to offer rewards for the defeat of Aklash, the leader of the Great Goblin's elite soldiers.
'The information you recovered is invaluable, ${PLAYER}. With it, we now know many of the goblin-leaders holed up in Goblin-town. Master Glóin would like you to find and kill Aklash.
'Notes on the letter suggest that Aklash is the leader of the Great Goblin's soldiers. It is likely that you will find him in the Great Goblin's throne room.
'Goblin-town is to the north-east and the throne room can be found at the end of the long tunnels of Goblin-town. Find him, defeat him, then return to me.'
Aklash is in the throne room of Goblin-town, to the north-east of Glóin's camp.
Tralli Gemfinder has asked you to find and defeat the leader of the Great Goblin's soldiers within the throne room of Goblin-town.
Tralli Gemfinder is at Glóin's camp, just outside the entrance to Goblin-town.
You entered the Great Goblin's throne room and found Aklash. After a harrowing battle, you defeated the goblin and should now return to Tralli Gemfinder.
