i'm gonna go ahead and say i think you are all wrong!!!
i think the narrator in DWoT is rather god/jesus
"eternal is my pain" like gods pain for seeing his children fall to temptation.
"mortals embraced thunder and majesty, their fate lays in our hands." because god would presumably be the one in control of the fate of mortals.
"i will devise a dark and vengeful day." pretty sure this refers to the wrath of god.
"this empty soul cries out one final plea." like gods patience has finally worn out, and he is making one last plea that people repent.
big one here "in disguise, you'll feel the wrath devine" satan is hardly divine, and this suggests to me its gods wrath disguised as things like plague and war and whatnot, like 4 horsemen stuff.
"standing on the edge of paradise, I sacrifice my truth and loyalty." god would be the one standing on the edge of paradise, like satan would be allowed that close
and sacrificing loyalty is finally giving up on those mortals whom he had given a chance for so long.
"the warrior brings judgement without compassion..." god and only god brings judgement.
antoher big one "the prince of truth now the bringer of war" i can only imagine the prince of truth is jesus who is now leading gods armies at the battle of armageddon.
"looking out on a blue sky, I can see a new world arrising" satan should have been destroyed after the creation of the new paradise.
"My paradise has begun" yeah gods paradise, satan doesn't have a paradise.
and you know putting all that aside, when it comes to singing, Russel is God anyway, so it should be obvious right?
