Background

The Underworld was originally described as belonging to the Dark Plane, the source of black magic. Undead can be summoned from it or contracted and stored in an Undead Mage's personal Undead Space; unlike ordinary summoned beasts, undead are notably difficult to destroy. 3 47

Jiang Yuan's early Undead Space was exceptional, opening before he possessed the Intermediate-level Undead Contract. Its ability to retain Soul Essences and Remnant Souls gave him an unusual connection to undead resources. 3 5 47

After gaining the Ancient King's status and the Imperial Seal of China, Jiang Yuan anchored the Abyss of Evil inside his Undead Space. This transformed the space into the foundation of a growing undead domain under his control. 72

Jiang Yuan later invaded the Egyptian Underworld through a gateway at the Red Sea. Following Khufu's defeat, the Eastern Undead Empire absorbed Egypt's undead territory and began conquering minor underworlds across the world. 218 221 223

Environment

The Egyptian Underworld is a dim realm where a gray, corpse-like sun hangs above ground formed from layered ash and unweathered bones. Its death aura is so dense that it rivals the Abyss of Evil despite covering a vastly greater area. 219

The deepest seventh layer contains Jiang Yuan's white-bone throne. From it, he can observe events throughout the Underworld and sense deaths in the closely connected main plane and Dark Plane. 238

The eighth layer, the Shadow Plane, is defined by jagged shadow mountains, black rivers, dense Shadow Power, and near-total concealment. Light entering it is silently devoured. 356

Sevenfold Underworld

The reforging process split Jiang Yuan's Undead Space into three regions, divided the Egyptian Underworld into two, preserved the Abyss of Evil, and incorporated conquered minor underworlds into a new seven-layer structure. 237

Layer	Domain / Ruler	Notes
Fourth	Scorpion Empire — Apas	Apas is permitted to rule the Scorpion Empire temporarily. 238
Fifth	Liu Xian	Initially offered to the Eight Directions Undead Lords; Liu Xian ultimately receives it while remaining loyal to Jiang Yuan. 238
Sixth	Austin, the Black Dragon Emperor	Austin accepts the layer and intends to bring dragons from Myriad Dragon Valley. 238
Seventh	Jiang Yuan	Site of Jiang Yuan's throne and residence; the Eight Directions Undead Lords and his summoned forces remain close to him here. 238
Eighth	Shadow Plane	Created from the Shadowkin King's origin and integrated into the Underworld. 316 356

Properties

Undead Habitat and Contract Domain

The Underworld supplies undead for an Undead Mage's summons and contracts. Contracted undead can be housed within an Undead Space rather than remaining outside the mortal world. 3 63

• Its death energy supports powerful undead populations, including numerous Lord-level undead in the Egyptian territory. 219
• Undead can be converted to Jiang Yuan's side through the aura spread by his Eastern Undead forces. 220
• Jiang Yuan's Super-level Undead magic can summon Lord-level undead, while Forbidden Curse magic can invoke Emperor-level power and create an Undead Calamity; as the source of the Undead element, he considers such spells redundant. 225

Soul-Gathering Potential

The Soul Divine Eye allows the Underworld to become more than an undead habitat by drawing in the souls of beings that die in connected planes. 283

• Souls ordinarily dissipate after death unless preserved as Soul Essences, Remnant Souls, or undead. 283
• Jiang Yuan prepares a ritual centered on the Soul Divine Eye to redirect this soul energy into the Underworld. 283
• The Underworld is later described as overflowing with souls, which Jiang Yuan intends to feed back into the plane for expansion. 315

Planar Expansion

The Underworld can incorporate other territories and planes under Jiang Yuan's authority. 237 267

• Conquered minor underworlds are physically brought back and merged into its structure. 237
• The Shadow Plane becomes its eighth layer after being created from Shadow Power and the captured Shadowkin King. 316 356
• Expanding the King of Underworld's Authority by incorporating further planes is identified as necessary for Jiang Yuan to approach the Heavenly Father's realm. 267

Rulers and Residents

• Jiang Yuan — Absolute sovereign of the reforged Underworld; rules from the seventh layer as the King of Underworld. 238
• Nine Nether Queen — Jiang Yuan's subordinate who gathers undead materials, leads intelligence operations, and helps administer expansion. 72 223
• Apas — Temporary ruler of the fourth layer's Scorpion Empire. 238
• Liu Xian — Receives the fifth layer and refuses Lilith's summons on Jiang Yuan's orders. 238
• Austin — Black Dragon Emperor assigned the sixth layer; leads campaigns against minor underworlds. 221 238
• Eight Directions Undead Lords — Jiang Yuan's long-serving undead forces; they prefer remaining at his side over independently ruling the fifth layer. 238
• Abyss of Evil — Anchored within Jiang Yuan's Undead Space and retained during the reforging of the Underworld. 72 237
• Dark Plane — The Underworld's original greater realm; later targeted for integration into the Underworld. 47 356
