I already brought this up but i think this should be used for further proof of not only Morgoth being High 3-A but all Valar (who downscale from him), basically he can affect all of Arda (the whole planet if not solar system) and potentially the whole Eä (the physical Universe itself).
"For they hold that the failure of their hroar to endure in vitality unwearied as long as their fear - a process which was not observed until the later ages - is due to the Marring of Arda, and comes of the Shadow, and of the taint of Melkor that touches all the matter (or hroa)(8) of Arda, if not indeed of all Eä."
There's also this:
"even left alone he [Morgoth] could only have gone raging on till all was levelled again into a formless chaos. And yet even so he would have been defeated, because it would still have 'existed', independent of his own mind, and a world in potential."
Whatever that means.
