"Another target for you in Swinedene's fjord area. Travel north to North Earlsome and head east."
How to Complete
Omar is on the hut area on the west side of Swinedene, not accessible from the main road. Like the quest says travel north from Longdale to North Earlsome, going straight north you'll run into Xuihcoatl the red wyrm dragon overlord, so you may want to take a few steps more towards the cave to avoid that spot. Defeat Omar to complete the quest.
[information what monsters Omar has goes here, I can't remember anymore sorry]
