Essence of Isolation "Can only hold one at a time"
I realized today that I left the Shadowkeep campaign halfway finished on my warlock. I need to obtain all Dreambane armor pieces to complete the next mission. However, I cannot obtain this essence, and it says that I already have it. My research shows that in the past that it would be in quests or postmaster, but I cannot find it in either. Since I have not obtained the piece yet, I cannot get it from Eris' abandoned quests. Any idea what is going on here? Thanks!
