Eos had not forgotten how could he ever forget the moment he stepped outside Existence for the first time and saw the true face of the dimensions and then saw the hand of the Painter in the distance… he had turned around and saw that the entirety of Existence, everything that he knew, loved, and hated was just a painting.
There were a few things that could shake him up to that extent, and this was one of them. Reaching the tenth dimension, he had seen many truths about what happened on that day, including the fact that the Painter had suppressed his ascension to the tenth dimension by hiding the truth of the Concept of Immortality from him.
The Painter could not directly claim Eos's immortality, or that would have alerted Eos to its manipulations, but he could cover this concept with darkness, making it harder for him to reach it, and until he fought till he emerged from Existence and fused with it, he was able to fully touch the concept of immortality.
