I read my quest log. I also killed every single non-invulnerable thing in that entire area, and looted every lootable. I even got into a fight with every single invulnerable mob there at once smile. Adventuring doesn't always find a solution to everything!

I guess I missed something. Maybe I'll have better luck on my next play though. Note my issue with that wasn't that I couldn't figure out how to do it (I'm happy to have more quests to solve), but rather not doing it (which should be fine) makes a mess out of the ambiance of the climax due to badly balanced audio in that particular case, which I assume isn't well tested since its likely new/improved in the latest patch and uncommon to do that way.
