Michael's Empyrean blade
Empyrean sword fight
Empyrean Steel is the celestial metal that angelic weapons and armor are fashioned from. The metal possibly originates from the Empyrean Heaven; the place in heaven, which is occupied by the element of fire.
Properties
Chemical Composition
On an elemental level, empyrean steel is composed of magnetite with 10.8% nickel, 9.2% manganese, 12.4% vanadium, and 67.6% of an unknown alloy.[1]
Effects
Wounds caused by empyrean steel do not heal, and if the blade is removed, can cause the angel to bleed to death. Earthly weapons and metals do not affect higher angels, but this angelic metal is able to harm, and even kill high-tier angels such as archangels and powers.
