The scenery is beautiful. I was drawn in by “a screaming comes across the sky.” So, so cool!
My thought on pace and structure is the same. Because you’ve used some “near rhymes” you might be able to draw on your use of rhyme to indicate a change in thought. Allow me to explain myself :)
The first four lines, you seem to be mostly examining. The second four lines you seem to wonder. You can break them into sections by changing the rhyme every four lines. “From which they come to wreak havoc” and then the final line would rhyme with “havoc.”
I looked up some near rhymes on rhyme zone so I wouldn’t leave ya hanging lol. You’ve got magic, planet, acid, dramatic, volacanic…. Just some ideas.
This was a great poem and I think you’re up to awesome stuff!
