Demon World.
Under the sky dense with thunderclouds, the Demon King Castle, shrouded in a layer of mist, appeared and disappeared like a phantom, accompanied by eerie music.
The deep-gray stone walls and the towering spires were faintly visible among the clouds, their tips nearly piercing the sky. Ancient runes twisted and intertwined on the barrier, silently telling the secrets of the Demon World. A winding path split the garden of the Demon World, piercing through the castle's many heavy doors.
Passing through the castle gate and down the corridors, the floor of the central courtyard was covered with complicated patterns of stone slabs, with an indoor fountain scattering softly glowing particles.
At the very depths was the throne hall, with corridors on either side lined with pitch-black armor, filling the hall with a deep and solemn atmosphere.
"Hmm..."
Hyperion slowly awoke from her slumber, letting out a tired hum.
