Before accepting the Flying Wings Quest, look for the Hidden Myth NPC in that area and accept and complete its quest. It's a book on a shelf on the second floor. Watch the first 45 seconds of the video. [youtube]https://youtu.be/HXFecDD7N_I[/youtube]
Do you enjoy riddles? Platform jumping? Quests that can only be done at night? Do you have tons of energy just sitting there wasting space? Well then this questline in your suggested tab has it all. Multiple jumping platform quests high in the air above Drieghan, multiple quests with no waypoints, quests where you get teleported back to the quest giver if you answer incorrectly, quests with answers that cost tons of energy to choose their answers, well then it's all here... ENJOY!
Seriously though, this has been one of the most annoying questlines. All you get are a few emotes and some junk...
