I agree when it comes to Esuna vs Dispel. That Elidibus might be able to unravel the illusion's effects from someone (after some study of it etc) because of his standing as a mage++ is something I have not questioned after because he's already doing a lot of things. He would have a lot of reason to leave a lot of people IN the illusion's grip more than free them. (You know how it goes. Too much mass panic from a lot of people suddenly realizing they're in an illusion etc etc). So other than efforts of studying the illusion's construction and composition, he's not actually doing a lot toward direct effort at freeing people, relatively speaking. But he would explain this too if asked why he's not.

I think I like your idea and I will start a thread in case there's others who are looking to consolidate their ideas! Elidibus might not be keen to free everyone right now but EVENTUALLY they'll need to be restored. Is it normal to make it in the OOC comm?
