In order to repair the bridges in the Flaming Deeps, the dwarves need iron to forge braces and supports.
'I no longer have the iron I need to build the braces to support the failing bridges.
'The Ghâsh-hai have many iron weapons. If you were to collect some and bring them to me, I could melt them down and be able to make what we need. You can find the Ghâsh-hai roving all over the Flaming Deeps.'
Ghâsh-hai swords can be found on the Ghâsh-hai, roving throughout the Flaming Deeps.
Ulfied needs Ghâsh-hai swords to melt down so he will have the iron necessary to build repair struts for the bridges.
Ulfied is at The Cross-roads of Ash, in the south-west portion of the Flaming Deeps.
Ulfied will want to begin melting down the Ghâsh-hai swords as soon as possible.
