My theory is this

Do you know the theory of frequency…

Like every object has it’s own frequency and if you manage to produce a sound to match or exceed that frequency that object will shatter

Like an opera singer an a wineglass Okay. And then, The other theory of frequency is about parallel worlds

That all of us (parallel universes) exist on the same plane of time and space

But we vibrate on different frequencies and that’s why we can’t see each other

(I’m talking about the frequency of matter and not the wineglass thing) What if the demigod world exists but on a different plane of existence but we are still able to see each other due to some anomaly

Now… Frequencies can be transmitted am I right? What if the monsters, hellhounds etc, don’t *smell* demigods but actually *hear* them due to their unique frequencies

Now… This would explain why demigods aren’t able to use wireless tech because that would only broadcast their frequency even more

Right? And what if the mist, isn’t a physical thing, it’s just the fact that us humans can’t see into their world as easily as they can see into ours. And our brain perceives the different bits and pieces and tries to make sense of it

Hence… The mist

And that time Morpheus knocked all the mortals out. What if he just generated a frequency that only they could hear

I can’t explain the time thing or the other stuff but there’s something to it

-I know I didn’t explain this well but it’s like 4 am here, I just thought of it.
