I am a returning player that has a level 75 character and an active subscription. I can't seem to find a quest to launch the new expansion story. I read that I must complete some previous expansion quests but I can't figure out which ones. I have the quests Lingering Darkness, Progress Report, and Ossus Defense in my log which I think are from the last expansion. Is it one or more of those questlines that I need to complete?
