It's the one quest in Mor Dhona, not the one to unlock the dyes.
After you spoke to a NPC he send you to another NPC in Rowenas house. After you talked to this NPC (" Hey guy, the other guy is worried about you") you finished the quest and can then give him specific items to augment your AF.
I don't know why he think this is a DoH quest. In the whole quest no crafter is required. Getting the stuff for augments is also not required in the quest.
