What about spiritual planes? Wyrm live in the spirit realm, plus if the specific wyrm I mentioned earlier shows up (if was in its most powerful state before its death) then it would also have control over evil energy which can erase whatever it touches
For context a Wyrm is a being which can take the abilities of whatever it eats. And are essentially immortal if they just make an egg before they die (the version of them with the new abilities bursts out of the egg) one such wyrm constantly adapted during a fight by continuing to lay eggs inside of itself
