The Bottomless Abyss.

The thick crystalline pillars on his back are like mountains on the back of mountain shifting tortoise except that they are more in number and vary in length. Their appearance makes it more accurate to call them lodestones rather than mountains. The 9 of them account for most of his weight. 

They were previously unseen before Ragnarok began to engorge himself on the world. But they began to glow an eerie blue glow as they stored the energy he devoured within himself. They shined brightly in contrast to the darkness around his 10 tails. 

The light he is producing does not feel one with hope as Rinoz's did. He doesn't look like the hope of the plane at all. There is a dark whirlpool around him while he is the light at the eye of the whirlpool. No one mistook him for salvation. Instead, He looks like the herald of the end of the world. 

"This is new." He thought to himself as he watched the Carnage that he wrought.
