Warding Runes  

'I have further examined some relevant records, Bludless, and I think I may have some new information...these rune-rocks were used to ward off evil creatures in the deepest delvings during Durin's day. But I wager they had never seen the nameless horrors we have uncovered!

'And yet...I have a feeling that the rune-rocks may prove crucial, somehow. You may laugh, but when I follow my feelings, good things tend to happen. Let us follow this one, shall we?

'I think that if you press the runes on one of these rocks in the right order -- don't worry, I will teach it to you -- they make a strange sort of writing. More of an idea, really; an idea of light, and civilization, and truth, and honour, and courage. Will you try it?'

Wéorn thinks that the rune-rocks can be used to ward off an ancient evil, or at least mitigate its powers.

Use the rune-rock and defeat the Rock-warden

The rune-rock lies near Mazam-dûm, on the eastern shore of the lake in the Foundations of Stone.

Wéorn would like you to press upon certain runes on a rune-rock in order and see what happens.

To get there (yeah, this is confusing): bottom of the Refuge ramp go south to the T, then right. Kill a mob or 2 and take the first tunnel left. At the end (another T) go down-left, Keeping going down until you reach the lake. Swim legthwise accross the lake (past the Bridge Shard) to a ramp on the far side. Take the first and every right that you can and you will find the Rune Rock on a ledge overlooking the lake.
