'The Orcs of Moria seem to be of a limitless supply, Name, but the weapons they wield seem to be much less available: every sword or axe we take from them is an Orc we render defenceless, if only for a short time.
'The orcs have established camps to the north-west along the road that runs through Nanduhirion: Uruk-gashan, Dru-garmadh, and Athmadhul. Journey to these three camps and steal any of the weapons you find within.
'I will not forget any of your deeds against the Orcs that have invaded Nanduhirion, so perilously close to Lothlorien.'
Maethoron knows that the Orcs of Moria are more limitless than the weapons they wield, and wants you to steal some of these weapons from the Orc camps in Nanduhirion.
