The Astral Line & Pandemonium Engine
The invisible river of spiritual energy that flows beneath Earth and Hell. Demons require Astral energy to maintain their physical bodies and powers. Controlling or severing the Astral Line allows high devils to manipulate life, death, and spatial reality.
The Seven Apostles & Divine Resonance
Miraculous Birthmarks · Astral Channelers
Seven rare human children born with sacred marks that grant them direct control over Astral energy (such as Azmaria's healing song or Joshua's time manipulation). Aion hunts the Apostles to siphon their divine resonance and rewrite the cosmic order.
Aion's Horn-Grafting Experimentation
SPOILER!
Biological Weaponization · Astral Overload
After stealing Chrono's horns centuries ago, Aion grafted them onto Joshua Christopher. The raw demonic energy corrupted Joshua's mind, granting him time-freezing capabilities while triggering disastrous chronological distortions across San Francisco.
