Even that gaze made her feel a sense of inexplicable familiarity.

Spirit Realm.
"Tens of thousands of years" had passed since Hypnos had seized control of the Spirit Realm, and he had begun his plan to enter the dream world.
He first lured some weaker deities into dreams, then let their primary consciousnesses immerse in false dreams, their physical bodies at his disposal. He eroded Olympus with a war among mortals called "Troy," then successively devoured the Underworld, encompassed the stars, and even the Primordial Gods were no match for him.
He ruled over heaven and earth, governed the sun, moon, and stars, but he did not accept the position of Divine King in the current world, simultaneously becoming the master of both the material and spiritual realms. Because the God of Sleep felt that the Spirit Realm should be above the Mortal Realm, not equal to It.
In the end, when Hypnos stood at the pinnacle of Chaos, his gaze turned to the world itself.
