Everyone knew what happened afterward. The Prehistoric Avengers drove off the Celestials, and to oppose the Trinity of Ashes, who also occupied the Splitting Domain, Oshtur formed the three-member Vishanti.
Then came all manner of dimensional wars, continuing until the present day and forging the illustrious reputation of the Trinity Vishanti.
During one break, Oshtur even put on her Goddess of Justice Ma'at persona and went to have some fun among the Eternals of the Egyptian Pantheon. Even now, Egyptian murals still depicted a goddess with a bird's head striking all sorts of comical dance poses. That was her.
After conducting a thorough investigation, she found that the Eternals, those advanced lifeforms created by the Celestials, were essentially rubbish with bizarre stances and no sense of right or wrong. They were destined to be abandoned by history, so she never paid attention to them again.

She could only swallow her anger and endure it. She stopped letting the angels deliver letters
