Dindal fears the Orc raiding parties that come out from Harlond. Though they are small, they may discover Lossarnach's weak points and report back to the larger force.
'I will tell you what I fear most. It is not the Orc-host below us, for they look north. No, it is the raiding parties I have seen. Though small in numbers, what they may glean and report back... where we lie undefended and un-pillaged, what farm remains yet unburned... these are troublesome thoughts.
'There are abandoned scouts' camp-fires in the wooded groves along the mountain's feet. If you built smoky fires in these, you might draw small parties of Orcs towards you, and dispatch them before they could go farther south.'
There are wooded areas west of the Harlond and the road leading up to it.
Dindal has suggested that you start smoky fires at old camp-fire sites in wooded areas near the Harlond, in order to lure Orc raiding parties to you in small groups.
Dindal the scout can be found high up in a secluded look-out, which can be reached by turning north off the east road from Imloth Melui.
You should return to Dindal and let him know that his plan worked.
