I've been trying to get my newest level 100 to get the Delgarath attunement quest. I've talked to Jarthur, did three quests from him leading up to the Island of Talinis. (I soon learned that this was not the correct path as a character who was already attuned to Delgarath had not completed this quest.)
Gulnor only offers the two lore quests (I thought he started it?) so looks like I have a bit more to do above ground before I can start it.
Went to Delgarath and did quests for the militia only to find out Carmichael was alsking for a Murk Crab shell, something I could obviously not produce.
Near as I can figure, the quest line leads to another NPC but I have no idea which one.
