The power of the [Ghost] is truly terrifying.
Even the Greedy Demon God, who possesses [Steel] Ability, cannot exert the slightest strength in the dream.
This terrifying existence that kills in the dream can easily massacre any creature, including the legendary Innate Myth in history.
During the First Epoch and the Second Epoch, the casualties caused by [Nightmare·Ghost] were astronomical, and countless civilizations trembled in fear, deeming it an "unsolvable existence."
Until later, a [Demon] possessing dream ability, by chance, took over this [Ghost], alleviating this massive crisis.
But there was a price to pay for taking over the [Ghost]; the power level of the [Ghost] was indeed too high, causing the [Demon] to be able to stay awake for only a short time and then must enter long periods of sleep.
Moreover, after the [Ghost] was taken over, its combat power significantly decreased.
This made the significance of this possession minimal.
