The first technique to manipulate the Proto-Dimensions was born, distinct from what the Beast was given by the Temple, after all, that technique was uniquely suited for the Beast to explore the past, and not for anyone else.
What Eos had created was different, but as he observed the makeup of the technique, for him it was ultimately useless because, unlike the Beast of Final Rest, there was no similar Origin like him for him to trace into the past, and any attempt he made was useless and a waste of energy.
This unknown dimension of the past was unexplored territory and was so vast that it could be seen as infinite.
Gaining this first technique was opening the door to this new dimension, and Eos stopped for a while, dispersing the cloud of still-time around him so he could attend to a pressing annoyance.
