Heaven's Gate and the Undead Legion

Heaven's Gate is the Mythical Guild founded by Lux, while the Undead Legion is the evolving military body created through his necromancy and the independent commands of his named creatures. They overlap without being identical. The guild includes living adventurers, family, Slimes, beasts, craftspeople, allies, and residents; the legion includes skeletons, zombies, liches, named commanders, Covenant members, and forces raised for particular campaigns. Together they turn Lux's private ability to summon the dead into a community capable of protecting cities and worlds. (Chapters 354–366, 541–589, and 757–780)

Their importance comes from the ethic organizing that power. Lux names and improves undead rather than treating every summon as disposable ammunition. Diablo, his first skeleton, becomes a battlefield leader; Asmodeus develops into a strategist able to recruit and command an arcane host; and the Necromancer's Covenant formalizes relationships with willing living or dead companions. Heaven's Gate similarly grows through negotiated trust rather than automatic submission to its guildmaster. That principle is imperfect—Lux still animates enemy corpses and uses terrifying tactics—but it determines who is protected, how power is shared, and why the final dead answer his call. (Chapters 10, 477–511, 668–680, and 1217–1221)

Founding and identity

From private summons to a guild

Lux begins necromancy after reaching Elysium and evolves his first skeleton summon into Diablo through Skill Evolution. Early battles in the Kobold Nest and around Leaf Village teach him to combine maps, terrain, buffs, forced duels, Slime support, and undead pressure. The group is not yet a formal legion, but its operating pattern is already visible: Lux protects vulnerable people, gives each unit a specialized task, and treats named creatures as partners whose growth matters beyond one encounter. (Chapters 10, 57, 97–123, and 163)

The Sacred Dungeon provides the institutional foundation for Heaven's Gate. Clearing its gates gives Lux the right and resources to establish a Mythical Guild, a prize important enough to attract royal, military, and factional interest. He initially conceals the guild behind Twilight Rain's name while negotiating with Wildgarde's guardians. Rather than hoarding every advantage, he offers crafting benefits and dungeon access in exchange for cooperation. The arrangement converts a personal reward into a shared strategic resource and gives the new guild protection from powers that might otherwise seize it. (Chapters 329–366)

Lux tells Iris the truth because secrecy has already harmed those closest to him. Her acceptance confirms that Heaven's Gate is not merely an interface or title; it is becoming the institutional form of relationships he intends to preserve. The adults who remember him as Wildgarde's sickly child begin treating him as the responsible head of a growing organization. Yet authority remains contingent on judgment. Companions follow him because earlier expeditions proved he will assess danger, accept risk, and bring people home, not because the guild system erases their independence. (Chapters 354–366 and 439)

Name, secrecy, and public position

The name Heaven's Gate acquires political danger as quickly as prestige. Mythical Guild benefits, Sacred Dungeon access, and Lux's unusual class make the organization a target for empires, dragon factions, assassins, and religious authorities. Early concealment is therefore defensive. Members can coordinate through guild functions while outsiders remain uncertain about ownership, strength, and headquarters. This compartmentalization buys time for alliances and construction, but it also causes friction when trusted companions believe Lux is withholding risks they have a right to share. (Chapters 354–366, 439, and 659)

Public recognition gradually becomes unavoidable. Guild members intervene in continental wars, enter Domains, negotiate with rulers, and defend one another against Rankers. Cethus's willingness to stand between the group and vastly stronger enemies demonstrates that belonging has become more than access to rewards. Heaven's Gate is a chosen affiliation able to compete with race, kingdom, and inherited duty. Its humor and irreverent guild chat reinforce that identity: the members can mock one another while still rallying physically when the danger becomes real. (Chapters 586–659)

Organization and membership

Guildmaster and living community

Lux is founder, guildmaster, principal strategist, and the supernatural center connecting the guild to its undead forces. He allocates scarce opportunities, chooses expedition leaders, controls many summoning and spatial functions, and represents the guild before rulers. His authority is broad but not absolute in practice. Cai, Keane, Iris, Eiko, and other companions bring their own obligations, forces, and judgment. Lux can exclude someone from a mission, but doing so may damage trust even when his motive is protection. (Chapters 362–366, 407–439, and 657–706)

The guild expands into a household. Vera, Adeline, Lux's partners, young Slimes, undead companions, and visiting allies occupy social roles that cannot be described by military rank alone. When Adeline arrives, Heaven's Gate offers her a castle, community, and recovered family after decades of threat. Iris, Cai, and Aurora negotiate that inclusion among themselves rather than functioning as prizes assigned by Lux. Later marriages and children make the restored guild a literal multigenerational home. (Chapters 1057–1087 and 1225–1233)

Eiko embodies the overlap between family and command. Reborn as a young Slime connected to Lux and Iris, she organizes Baby Slimes, distributes resources so weaker companions can defend themselves, and later commands the Boom Boom Pirate Crew. During the Abyssal crisis she brings sea forces and Demigods to battle, briefly takes responsibility for Heaven's Gate, then delegates routine administration to Garret because her own strength is needed elsewhere. Her choice shows a mature organization separating battlefield command from daily governance rather than equating love for the guild with personal control of every task. (Chapters 366–434 and 1137–1166)

Named creatures and the Covenant

Named creatures are the durable core of the Undead Legion. They possess individual skills, pages, evolution paths, temperaments, and relationships. Diablo advances from a fragile skeleton into a mounted Death Sovereign who anchors the front line. Ishtar specializes in eliminating priority targets; Pazuzu provides defensive control; Asmodeus combines necromancy with strategy and mass magical fire; and later commanders add mobility, fortification, curses, or specialized authority. Their roles are complementary, so a large force becomes more than a numerical flood. (Chapters 10, 295–296, 541–589, and 715)

The Necromancer's Covenant allows a limited number of willing living or dead creatures to form deeper bonds with Lux. Consent distinguishes the Covenant from indiscriminate corpse animation, while the thirteen-member ceiling forces selectivity. The bond grants continuity and development, but it does not make every danger reversible. Named summons can initially be unavailable during cooldowns, living partners can die, and even powerful undead can be overwhelmed when an enemy attacks their souls, summoner, or shared battlefield structure. (Chapters 668–680 and 757–780)

Asmodeus demonstrates increasing autonomy within the legion. His Lord's Equal title lets him mirror much of Lux's skill set, but his value lies in applying those powers through his own judgment. He builds traps and fortifications, raises or recruits spellcasting undead, and ultimately arrives at Agartha with more than one hundred thousand liches, skeleton archwizards, warlocks, and sorcerers. Some are created from the dead; others are sentient undead won through persuasion or coercion. He can direct their combined artillery around allies, showing that mass necromancy remains dependent on command precision. (Chapters 1137–1138 and 1187–1200)

Guild infrastructure

Sacred Dungeon and shared growth

Access to the Sacred Dungeon is Heaven's Gate's first major institutional resource. Dungeon slots can raise fighters and factions, so distributing them is political as well as practical. Lux refuses to let one interested power monopolize access and uses allocation to build cooperation among Wildgarde, royal forces, guilds, and other allies. Keane and Cai support the decision despite having opportunities to claim more for themselves. This establishes advancement as a coalition-building tool: the guild becomes stronger by making reliable partners stronger. (Chapters 354–366)

The same principle guides expeditions. In the Domain of the Fallen, Lux suppresses factional arguments, uses the Elysium Grand Compendium to identify routes and concealed monsters, and assigns roles according to capability. Maps and appraisal do not replace courage or combat power, but they prevent a coalition from wasting lives against threats it cannot yet defeat. The guild's logistics—information, storage, communication, crafting, and transport—are therefore as important as spectacular undead summons. (Chapters 407–439 and 660–667)

The floating island

Heaven's Gate's headquarters becomes a floating island connected to the Giant Earth Turtle. Mobility is a defensive answer to the Divine Army of Light and other factions able to attack a fixed, unfinished base. The island contains the guild's castle, town, residents, family spaces, and strategic facilities. Joining it to a living colossal creature also makes the stronghold more than ordinary property: its movement, survival, and eventual resurrection depend on the condition of the being carrying it. (Chapters 781–782, 1086, and 1209–1225)

The final war proves both the island's value and vulnerability. Daniel targets it with an Outer God's power because destroying the headquarters would kill civilians and break the community defending the gates. Keane completes Grand Void's final stance by sacrificing his life to split the beam. Half the island is lost, but the town and guild headquarters survive. The scene makes infrastructure itself a battlefield objective: preserving the people and institutions at the center matters more than keeping every section of territory intact. (Chapters 1209–1211)

After victory, Lux restores the ruined island because its fusion with the Giant Earth Turtle allows him to resurrect the whole structure as a living entity. This restoration is not simple repair and does not imply that any building can be revived. It depends on the island's particular union with life and on Lux's postwar authority. The recovered headquarters becomes the physical proof that Heaven's Gate survives its members' deaths, memory loss, and displacement without pretending those events never happened. (Chapters 1221–1225)

Military doctrine

Combined command

Heaven's Gate fights through layered roles. Lux and Asmodeus coordinate summons and battlefield geometry; Diablo applies frontline pressure and auras; defenders compel dangerous enemies to focus on them; assassins remove priority targets; ranged units exploit openings; Eiko contributes Slime replication, artillery, and later naval forces; living specialists use professions and racial abilities the undead do not possess. The doctrine is strongest when each participant has a defined responsibility and enough information to act independently if the central plan breaks. (Chapters 110–163, 291, 477–511, and 541–589)

Necromancy makes attrition unusually flexible. Lux can animate enemies, detonate corpses, replenish ordinary units, and preserve selected bodies for more valuable commanders. These tools are morally and tactically constrained. Corpse Explosion becomes unacceptable when allied troops are mixed into the target zone; named summons have cooldowns or individual vulnerabilities; raising a powerful being may require resources and compatible skills; and using the dead carelessly would contradict the loyalty on which Lux's sacred class later depends. In the Yelan–Ammarian war, he uses a sinkhole and controlled necromantic pressure to collapse enemy formation while limiting friendly losses. (Chapters 477–511)

The legion also includes forces not created directly by Lux. Eiko's pirate crew, allied Slimes, dragons, sea powers, and Asmodeus's recruited sentient undead preserve their own chains of loyalty. During later wars, Heaven's Gate functions as a coalition headquarters that aligns those forces against a shared threat. This makes its name broader than Lux's personal summon list: a combatant can defend Heaven's Gate without being undead, bound, or formally dependent on his class. (Chapters 905–906, 1137–1166, and 1202–1219)

Holy and unholy power

Lux's recognition as the first Heaven's Necromancer changes the legion's metaphysical basis. Under Gaap and the restored Hereswith, he learns to unite holy and unholy power and grant peace to trapped souls. The Divine Army of Light calls the result heresy because it challenges an order that identifies necromancy itself with corruption. Lux's class instead judges practice by responsibility toward the living and dead. His undead answer faith and relationship, not only an imposed command. (Chapters 668–680 and 757–782)

Deus Gigantia expresses that synthesis on a massive scale. It combines the power of Lux and his forces into a war form capable of contesting high-ranking enemies. Asmodeus later merges his forces into it and eventually summons an expression of his own. The construct is not an effortless victory condition: against Demigods, Abyssal rulers, and Outer-God power, it depends on the condition of its contributors and can be exceeded. Its real importance is organizational, making the legion's accumulated development function as one coordinated body. (Chapters 843, 905–906, 1099–1105, and 1187–1210)

Historical campaigns

Continental wars and dragon politics

Inside the Gate of Conquest, Lux intervenes in the Yelan–Ammarian war and scales necromancy from party support to army command. His plan breaks the opposing formation, deploys commanders into the breach, and ends a prolonged campaign. Later conflicts with Flamma, empires, the Crystal Palace, and dragon powers test whether the guild can protect members without becoming another conquering state. Its answer is alliance, deterrence, and selective force rather than territorial annexation. (Chapters 477–511 and 586–667)

The Dragon Kingdoms and Abyss extend Heaven's Gate's network. Lux's cooperation with Aurelia begins through competent shared command rather than immediate political submission. Gaap's history with the Divine Army makes the floating island a target, while Queen Rhiannon's war forces the legion against Demigod-led armies. Eiko, Gaap, Antero, dragons, and undead prevent Lux's command from becoming isolated around one race or one world. (Chapters 660–782 and 843–906)

Divine Army, Twilight Rain, and invasion

The Divine Army's persecution of righteous necromancy creates a conflict over who may define sacred authority. Lux's class and Hereswith's legacy expose the institution's violence rather than resolving every religious question through greater force. Heaven's Gate survives by combining mobile defense, alliances, and the credibility earned across earlier campaigns. Its continued existence becomes evidence that undead power can protect souls instead of exploiting them. (Chapters 668–782 and 905–906)

Against Twilight Rain, Lux coordinates with the Order of the Griffin and allied rulers to end the long conflict that once forced him to stage his death. He does not replace the defeated organization as a clandestine ruler. The guild instead provides safety for Adeline and a home in which Lux can reconnect with the family severed by those wars. This movement from vengeance to shelter is central to Heaven's Gate's purpose. (Chapters 1035–1087)

Daniel's invasion nearly destroys that purpose. Lux rises to S-Ranker, fights with Deus Gigantia, and is almost killed stopping Nuclear Chaos from reaching Solais. Divine intervention severs routes between worlds and makes most people forget him. Unable to summon his companions or rely on formal guild authority, Lux must return and rebuild personal bonds without forcing memories back. The episode shows that Heaven's Gate ultimately rests on relationships deeper than the interface, even though supernatural loss can temporarily erase their conscious history. (Chapters 1099–1127)

Final defense and restoration

The final war brings every layer together: the floating island and its civilians, Eiko's forces, named undead, Asmodeus's army, living guild members, allied rulers, divine relics, and the gates to Heaven. Members repeatedly reject Lux's attempt to bear the danger alone. Keane dies saving the headquarters, and other companions fall while holding the path against Daniel. Their choices turn the guild's accumulated trust into the immediate condition for Lux's ascension. (Chapters 1202–1217)

At World's End, the dead of the battlefield answer Lux, followed by the dead and undead of the wider universe. Yog-Sothoth carries the call across worlds, and Lux becomes guardian of a golden gate. The response is not simply a larger summon spell. It is the cosmic extension of the promise first represented by Diablo: the dead recognize a commander who has spent his life treating their wills and sacrifices as meaningful. (Chapters 1217–1221)

After defeating Daniel, Lux refuses godhood and uses the Five Pillars of Eternity to return fallen allies to living bodies rather than preserve them as bound undead. He then rebuilds the island and helps cleanse Solais of Abyssal occupiers who murdered civilians, while sparing those who did not abuse the population. Restoration and judgment replace permanent mobilization. Heaven's Gate survives as a home because its strongest power is used to release the dead from service. (Chapters 1221–1225)

Postwar role and significance

The Elsoetia Olympics show the guild's world-linking authority turned toward civic life. Lux and William connect Elysium, Solais, and Hestia through a contest with public rules and a limited wish. When Eiko's enthusiasm disrupts the final race, they allow recovery and a fair restart, then honor a tie. The same organization that coordinated undead armies now uses cross-world access to create shared festivals rather than a private empire. (Chapters 1230–1231)

Heaven's Gate's lasting significance is the union of differences normally treated as irreconcilable: living and dead, holy and unholy, Solais and Elysium, guild and household, private affection and public command. It does not erase those distinctions. Named undead remain undead until specifically restored; allied kingdoms remain separate; family members retain their own choices; and the guild's history includes secrecy, corpse use, political threats, and catastrophic loss. Its achievement is making cooperation durable without requiring sameness. (Chapters 668–782 and 1209–1233)

The endpoint leaves the institution active but does not provide a complete postwar roster, census, or administrative charter. Lux accepts possible service with the Sentinels and opens Heaven's Gate toward threats beyond the worlds already saved, while marriages, children, restored companions, and the rebuilt island continue behind him. The narrative therefore establishes a transition from continental guild to cross-world protective community, not the final boundaries of its future jurisdiction. (Chapters 1232–1234)
