Bring Eckinish to Dagma QuestDagma, the farmer Thurwin's wife, at Lava Lake requires some Eckinish plants from the Abbey of Thule to Cure her Lung sickness.
You can get Eckinish from Brother Joram in the Abbey Gardens to the west of the Abbey of Thule.
He has not given me this thing until I've completed some quests... Perhaps my persuade skill became good enough to convince him. (edit: I had no trouble with this, but my persuade was 55 before bonuses!)
After this is done Return to Dagma's house at Lava Lake and receive a reward.
