For a higher-dimensional being like Eos, Time was not an abstract concept; it was a road, and it only needed the right amount of power to walk that road. If he wanted, he could send an Incarnation of himself into the past, but due to the weight of his Existence, he could not change the future in this manner; it would be highly costly and nigh impossible.
If anyone could observe the river of time, they would see that Eos and certain entities were like massive mountains in a shallow pool, and time could only helplessly flow around them, while the Primordials were like small hills, and everyone else, even the so-called immortals, were being slowly dragged by this river.
Also, if Eos were to go back in time, he would see something peculiar: some of his children were missing, like Andar, and even his mother was gone, leaving only a void.
