The plane won't last longer anymore. The fact that its anchor has been exposed means it is very close to its end. When it ends, the demon god plans to kill both Ragnarok and the fountain of life for the artifact.
Then it remembered that it wasn't alone. There's someone else here that could threaten it. It made the Supreme of Carnage groan and complain. "Of all the time for this muscle head to show up, now is the worst time."
"I have to stop WRATH. Let me distract this flame head for a while."
It doesn't want to fight anymore. A fight is the last thing on CARNAGE's mind now. So It sent out a portion of its body to fight the demon god of WRATH. It should delay WRATH and buy it enough time for the plane to end. Unfortunately, the delay tactic didn't work. The plane lasted longer than it should have. The demon god of WRATH arrived before the plane collapsed.
"Revenge is the sweetest thing I know." WRATH said with unbridled excitement when it got close.
