Imák and Venko think you should return to the leaders of the Gabil'akkâ with news of both the Angmarim cultists' plans and the peculiar visions the three of you experienced in Câr Bronach.
'There is something about Gundabad that is affecting us in this fashion, ${PLAYER}, but what it might be is beyond this Zhélruka's ken. I do not like it, and I do not trust it. I have no need for Imák's sense of smell to tell you the odour of this is foul!
'But for now we should return to Durin and Prince Ingór, and tell them of the Angmarim's efforts to use the Máltagar to break the wards on Gloomingtarn. Speak to me if you are ready, and we will hurry back to Máttugard!'
Venko is at the Witch-gate, waiting to speak with you before the three of you depart for Maergrind, the Noble Gate.
Durin is at Maergrind, enraged by both Gorgar's attack and the words of the Orc leader.
