In a world of myself

This a story based on a god of a galaxy who had woken up from a long sleep while remembering watching his people die and ignoring there prayers and went to sleep of being tired of listening to them while casting a note to let one person know of him sleeping without closing the location of the portal since he knew the person he sent the note was immortal and didn't bother since staying up for too long has tax on the body since he is the one maintaining his universe from outsiders from different galaxy from invading to break his core to conquer his people.
