The Angmarim have gifted the Frost-horde with a number of dwarf-wights to act as guardians of their nests in Flogalith.
'The Angmarim have gifted a number of dwarf-wights to the drakes of Flogalith, and these unhappy creatures now serve as nest-guardians. If you find yourself at Flogalith you must slay the wights! We cannot allow this insult to stand! It is the least we can do to honour these dwarves, though they perished long ago.'
The Angmarim have given dwarf-wights to the drakes in Welkin-lofts.
You should defeat dwarf-wights in Flogalith.
You have slain many wights guarding the drake-nest. You should report your success to Molkha.
Molkha can be found on the frozen lake south-west of Fellgát.
