Even in the Underworld, the Hades Heavenly Ghost Stratagem was a stratagem of immense power. It could summon the Underworld's mythical Hades Heavenly Ghost, an evil creature that lived off consuming the souls of living creatures. Legend had it that the most powerful Hades Heavenly Ghost could match other supernatural beings of the Underworld.
With the Ghost Lair's ability, it was impossible for them to summon a Hades Heavenly Ghost that was too powerful. But any Hades Heavenly Ghost that they were able to summon would certainly not be an ordinary creature.
Shriek!
The Hades Heavenly Ghost let out a shriek as it stood on the crimson moon. A unique sound wave spread across the entire ancient city.
Splat!
