It would be even better if Thalassar's rampage dragged on, causing significant damage to the Order of Ember. This way, the Hightower could regain some of the influence they had lost when Golden Scale's plan backfired.
(Recap: The Golden Scale's plan was to let Daniel crumble under the immense weight of responsibility, thus creating chaos for him and diminishing his influence. At the time, Daniel's name carried considerable weight as the most powerful mage and artificer, attracting many mages to his camp, which in turn weakened the Hightower's influence.
On top of that, the Hightower had nearly exposed the existence of magic to the public themselves, forcing them to shift responsibility to Daniel. The Golden Scale believed that as a newcomer, Daniel wouldn't be able to manage the Curtained World, but they were wrong. This miscalculation led to a significant loss of influence for the Hightower in the Curtained World.)
