The Taughâsh tribe which guards the Mirk-eaves against invasion use Wargs and Warg-riders to patrol the beachhead.
'A problem has arisen for the Malledhrim, my friend. Our forces are being harried by groups of Warg-riders who are ranging throughout the Mirk-eaves. Normally, we rely upon speed and our superior skill in battle to ensure victory even when outnumbered, but the Warg-riders' great speed allows them to harry and assault my soldiers at will.
'We need you to help thin out their numbers and keep them at bay...at least until we have secured the Mirk-eaves from the Enemy. When you have done this, return to me for further instructions.'
Taughâsh Riders can be found throughout the Mirk-eaves.
Fuirgam has asked you to defeat the Taughâsh Riders that have been harassing the flanks of the Malledhrim soldiers invading the Mirk-eaves.
Fuirgam's Aide is at Echad Sirion, on the eastern banks of the Anduin.
You should bring your report back to him.
