The memories he obtained were glorious ones that painted an immensely unique picture!
They also expanded what Achilles knew a tremendously as at this moment, he felt like he uniquely understood things that the vast majority of entities in these shattered folds did not!
Knowledge that THE entities hoarded jealously, understanding that separated existential significance from mere power.

When he observed the surrounding reality of the Sacred Holy Land of Alchemy, he experienced something that made his breath catch in his transformed chest.
He had an illusion…no, not an illusion but actual perception, as if he was seeing reality composed of waves and strings just like a THE entity would perceive it.
It had to be an illusion right? Because he knew that he had definitely not reached that stage.
