Glóin looked at the set of orders recovered from the Uruks in Goblin-town and found that they were also written in the Black Speech.
'We have no time to waste, ${PLAYER}. Take these directly to Master Elrond in Rivendell and beseech him to translate them. We have already been delayed too long.
'It is vital that we learn what the Uruks are up to. If they are able to muster the goblins of the Misty Mountains, who knows what force will be arrayed against us?
'Quickly now. Rivendell lies to the south-west, if you were not aware already.'
Elrond is at the Last Homely House in Rivendell, south-west of Glóin's camp.
Glóin realized that another set of orders written in the Black Speech would take too long to translate and sent you to Rivendell in order to speak with Elrond directly.
Glóin is at his camp just outside of Goblin-town, north-east of Rivendell.
Elrond Halfelven made marks upon the orders and warned you that the goblins had a new leader, a Great Goblin who was defiant of the Uruks' intrusion in Goblin-town. He sent you back to Glóin with the translated orders.
