Well, the pure power wouldn’t matter if it wasn’t concentrated enough to destroy the hröa their enemies was using to influence the Seen, I guess. Like they’d have first destroy their enemies physical being to be able to influence their incorporeal being?
And to do that, you’d want to focus your power, so you’d need a “lens” of sorts, meaning you’d use a body to fight the enemy?
Oh wait no, Morgoth didn’t have a physical body in that fight? Uh, I’d probably do well to read the Silmarillion again lol.
Well shit, does that end the theorising? So did Morgoth have a body or not whilst in that fight you were describing?
