Vatnar the dwarf has seen the Orcs of northern Gathbúrz moving catapults into position to attack Thangúlhad.
'So, we've managed to capture this tower, and it grants us a fine look at the surrounding land, but one thing I have seen that doesn't sit well with me is the Orcs moving a number of catapults nearby.
'The weather here in Mirkwood is not the finest at the best of times, but in a few hours it's going to include a fair hail of falling rocks, if you catch my meaning.
'Be a good sort and see if you can set a few of those on fire, would you? It is one thing being rained on day and night, but I'm not wanting a sharp crack on my head to go with it.'
Orkish catapults can be found throughout northern Gathbúrz.
Vatnar has asked you to destroy several Orkish catapults.
Vatnar is at Thangúlhad in Gathbúrz.
You should return to Vatnar with tidings of your success.
