The Moria Orcs have mined the Redhorn Lodes ever since the dwarves were wiped out of Moria. Recently, around the time the dwarves returned, so too did the White Hand Orcs. The White Hand aggressively wrestled a large territory from the Moria Orcs, and both are competing for control of the best mining location in all of Moria.
'Those blasted Orcs are stealing our ore! It's intolerable to see them stealing what should be ours. Dwarves found and built this mine first!
'I wonder what they're finding in the veins they've tapped into? It's one thing if they're smelting forms of iron or steel, but another thing entirely if they've managed to find mithril!
'Snatch ore from their dead Orc-fingers! It would be best to obtain ore from both tribes of Orcs to see what they've found.'
Ore is being gathered by both tribes of Orcs in large quantities in the central area of the large Redhorn Lodes cavern.
Bring the ore samples back to Róarr, camped at the bottom of the stairs on the way up to Orc-watch.
