You brought the remnants of an ancient, rune-engraved vessel to Mair among the cairns.
'I think the message upon this vessel may explain what has happened here. Perhaps in ancient days, a great evil was captured and bound to this place. Unfortunately, it would appear that the Dievlig have fallen prey to that evil.
'If you would, bring news of the message upon this urn to Naeglanc. Mayhaps, he will know better what it means.
'The Ranger is at his camp, Echad Naeglanc, to the west of here.'
Naeglanc is at Echad Naeglanc, west of the cairns where Mair is posted.
Mair has asked you to speak with Naeglanc regarding the remnants of the vessel you recovered.
Lhucu's hut sits upon a ridge west of Echad Naeglanc, between Lhan Gogledh and Lhan Bach.
Naeglanc suggested that you speak with Lhucu, daughter of Trehéarn Brenin, regarding the urn.
