James had received Mirabelle's invitation from the First Universe. He still had ten thousand years before the conference. That was plenty of time.
James returned to his seclusion sanctuary in the Human Realm’s Divine Dimension.
Initially, he planned to meet his family and friends before leaving for the First Universe. However, he decided not to see them yet after some deliberation. To them, he was already a dead man.
It was better they did not reunite since he would have to leave them again.
