Are the Shadow Isles Doomed?
Now that Illaoi has faded into existence from the Isle of Retcons, what's going to happen to the Shadow Isles vs. this priestess and her "White Mist" power?
The Black Mist and associated cursed fiends and characters seem powerless against the White Mist. The only person from the Shadow Isles that may stand a chance is Mordekaiser, as he's not really a Shadow Isles character to begin with (anymore). Although I think Morde could really care less about Shadow Isles as he's just using it as a place to hide his bones.
So can Illaoi just waltz into Shadow Isles and start wiping them out now? What is the narrative excuse for her never being around to ward off the Harrowing? And why was she not doing this to begin with instead of waiting until the last moment after so many people had died?
