I am planning on running a homebrew campaign, whose ultimate premise is that a villain is attempting to garner enough power to be able to eliminate all magic from existence. 

I am planning on setting this in the Forgotten Realms, but to avoid any confusion, I am excluding any of the other settings/realms from the equation (Grayhawk, Eberron, etc) to spare myself the headache of how a change of such scale would affect other realms.

I am aware that *a lot* will have to be done for someone to be able to achieve such a goal, but that's a question for another day. 

**So, mainly,** what effects would the entire removal/deletion of magic from the Forgotten Realms entail? Would Elves disappear, [owing to their magical nature?][1] What about dragons, and other magical creatures as well, such as the fey? Would the planes "collapse"? Would they cease to exist? Would only the Material Plane remain?

I know that I can simply change things up a bit in my homebrew to accommodate my vision, but I would prefer to first go off a bit of established lore.
