Have the Elementals ever protected the Shroud from anything?
Every bit of lore about the Elementals I can find is them smacking down random people for stepping on the wrong plant.
But invading Ixal, Garleans, and Ala Mhigans during the Autumn War are left unharmed. (Where is their Il Mheg moment where they go all forest scariness on an enemy army?)
I understand post calamity they were extremely weakened, but before that they seemed unwilling to defend the Shroud vs invaders. They only beat down the weak and isolated.
Might be best if the residents of Gridania find a way to permanently kill them now while they are weak before they regain enough power to kill small children for picking flowers.
