Thyrnir noticed that the Orcs of Gathbúrz have left their fire-oil supplies haphazardly piled about in the chaos of the Elven assault.
'Hello there, ${PLAYER}. Have you had a look down there in the Orc-camps yet? It's a real mess. Orcs and goblins aren't too good at staying organized when you put a good fright into them, from what I've seen.
'Anyhow, I noticed that they have got the oil for their siege-engines piled up in great heaps of boxes and crates, just lying about. That's dangerous...you never know when it might catch fire!
'If you were to steal a few of their fire-pots and use them to set the rest ablaze, I imagine it would help add a warm glow to these dreary slopes for the evening.'
Fire-pots and supply crates can be found in the Orc-forts throughout northern Gathbúrz.
Thyrnir has asked you to destroy the goblins' stockpiles of fire-oil by igniting them with the goblins' own fire-pots.
Thyrnir at Thangúlhad in Gathbúrz.
You should report your success to Thyrnir.
