The world before Ryuk could be described with one word.
Hell.
Not the literal hell those scrapped hunters used to curse themselves with—because Ryuk knew, if that hell was this, they wouldn't wish it upon themselves.
This hell was instead hell because everywhere Ryuk looked was covered in flaming, red, bubbling lava.
But what was worse?
"The steam from the lava was so hot, he could hear the lava-resistant rocks burning away, with entire mountains collapsing into the molten flow."
He watched them instantly reduced to ashes, before they even entered the lava at all.
His eyes roamed around, and he found that the space where he and the man stood was covered by a protective barrier, which was probably being used to shield the heat of the lava from reaching them.
Yet, Ryuk could still feel the faint burn on his skin.
As for how hot the lava would be, he had not the slightest idea—but what truly numbed him were the Fallens who were hung right above the lava.
Yes, Fallens.
