When Isiah eventually opened his eyes it was after a few seconds from closing them when he jumped toward the snake to save it from the dark rain.
Surprisingly it was not as bad as he thought, he has some misleading perceptions that followed him from when he was a human, and he needed to remove them so bad.
Now, the darkness was just another regular thing in his messed-up life. Blood, heat, dark atmosphere, and killing were just something that he needed to get used to.
He stood slowly as he was still covering the snake with his chest and then looked above him while raising his head toward the void..
As a former human, he only thought that there was a sky there somewhere but he couldn't see it, his mind was so shaped into ideas like that. Ideas that he found very difficult to remove.
Whenever he was forced to make a move, he found himself projecting it into his mind with human thoughts.
