Because the strongest core to ever exist got created so abruptly, the entire dungeon's existence came under threat. And since a dungeon is also a place where even godly beings could do nothing but watch, all the gods and goddesses became aware of the supernatural abnormality, but when they gazed into the dungeon to learn about the description and identity of the new existence, they noticed that they couldn't see the existence's face or feel his presence, even though they were directly looking at him.
None of the gods, goddesses, or transcended could see Eshwar's face because of the trait he took from Vinny, the "God Hater," which had been hiding him from the gazes of the gods and goddesses, who may try to make him their recipient, which he found to be too bothersome.
Of course, since Eshwar is the creator, he knew that the gods would peer into him, so he had taken a countermeasure, the "God Hater" trait, and he was sure it was enough to ward them off.
