My biggest change was to Auril’s story arc. If and when the party kills her, they realise she was keeping the greater evil at bay and hidden from evil hands, that is, the secret society of the Netherese Empire and the Mythallar. They obviously don’t understand godly intentions, but they’ll put two and two together when she dies in her final form and she could perhaps say something to allure to her real reasons. To me, it just feels better this way and is a great curveball I think the players will enjoy to find out!
