Earth–Axus peace treaty

The Earth–Axus peace treaty is the diplomatic state linking Earth with Axus through the betrothal of Hannah Delaney’s unborn daughter to Alvar, King of Underland. Its decisive consequence is that Lucy Hammond is not merely invited into another world but claimed as the future queen whose marriage is expected to prevent war. The treaty therefore joins peacekeeping, royal succession, bodily autonomy, and emergency security in a single arrangement: it promises protection for two worlds while making Lucy the price and instrument of that protection.

Origin and Purpose

The treaty begins with a promise Hannah Delaney makes to Alvar before Lucy’s birth. Lucy is expected to die in the womb, and Alvar’s people possess healing abilities unavailable on Earth. Hannah agrees that, if Alvar saves the child, Lucy will become his bride. The promise is thus presented as an exchange between a mother’s desperate appeal and a king’s intervention, but its consequences extend far beyond private gratitude. Hannah later explains that Alvar requires an Earth-human bride to preserve peace with his world, because some people of Axus are hostile toward humans and could attempt to attack and take control of Earth.

Alvar’s political reasoning is founded on the power of Underland. His kingdom is in treaty with every other country in Axus, and the other rulers will not dare attack Earth if Alvar commands them not to. The marriage is consequently more than a personal union: it is meant to make Alvar’s authority over Axus answerable to a cross-world alliance. Hannah’s account also makes the treaty’s coercive structure explicit. Refusing the arrangement would be treated as a grave insult to Alvar and his people and could provoke war, which she believes Axus would win.

Written Terms and Legal Force

Alvar eventually gives Lucy the physical agreement, an old, yellowed document written in bold black ink and signed by both Hannah and Alvar. It is sworn under Elias, the God of Light, and dated according to both worlds: October 10, 1993 on Earth and the twenty-third day of Havath, 2918 on Axus. The document identifies Hannah and King Alvar of Underland as the contracting parties and states that the female child Hannah carries will be betrothed to Alvar as his future wife and queen.

The stated purpose of the betrothal is to secure a peace treaty between the realms of Earth and Axus. Once the child reaches marriageable age, Alvar is entitled to return and retrieve both Hannah and her daughter so that they can reside in Underland. In return, Underland is required to provide their material and personal needs, the protection of the Underland Guard, and instruction from the Institute of Underland in the customs and ways of its people. The treaty therefore combines dynastic marriage with provisions resembling relocation, welfare, security, and cultural education. Yet its language grants Alvar the right to retrieve Lucy rather than describing her as a participant who may freely accept or reject the arrangement.

Enforcement Through Marriage and Protection

The treaty becomes an immediate crisis when Emily Hall is endangered after the women are caught in the conflict involving Maggort and Remora. Alvar tells Lucy that the only way to save Emily is to seal the marriage before the enemy discovers that the wrong bride has been taken. Once the marriage is completed, Alvar says, killing Earth humans will become a crime against Underland, and Remora will not risk war with him. He will then order Emily’s freedom and have her brought to Underland City.

This emergency converts the treaty from a distant childhood promise into an instrument of immediate legal protection. Alvar explains that marrying Lucy will allow him to declare all Earth humans protected; attacking them would then amount to declaring war on him. Lucy recognizes the absence of meaningful choice and protests that Alvar’s decision to claim her as his wife has placed Emily in danger while denying Lucy the chance to say goodbye to Mike Jones. The treaty’s protective promise consequently operates through a forced decision: Lucy must accept the marriage to obtain the legal status that can shield her friend and, eventually, other humans.

The wedding also reveals the difference between marital appearance and marital consent. Lucy states that she is marrying Alvar only because she must save Emily and refuses sexual relations. Alvar accepts that boundary, but insists that he spend the night with her because an old law requires the appearance of marital treatment if the union is to be taken seriously by the rest of Axus. The ceremony is held before hundreds of people in a chapel-like space. A human priest blesses the couple, Alvar drinks from a gold goblet, Lucy drinks afterward, and the priest asks them to seal the union with a kiss. Lucy meets Alvar’s kiss partly to appear legitimate before possible spies working for Remora. The treaty thus depends not only on signatures but on public ritual, visible conformity, and the political credibility produced by those performances.

Political Strategy and Moral Contradictions

Alvar later reveals that the treaty was also designed to isolate Axus from Earth if Saul returned. He had traveled to Earth while attempting to ensure that the tyrant king who had once ruled Axus would not return, arranging for Saul to be arrested by Earth authorities. Alvar knew that the imprisonment could last only so long, so he created a fail-safe: Lucy was dying as a baby, his blood could save her, and by marrying the adult woman she would become, he could secure a treaty that cut Axus off from Earth. The arrangement therefore has a defensive logic, but it also turns Lucy’s rescue into the foundation of a geopolitical containment plan.

That plan fails to eliminate the danger it was meant to contain. Saul returns despite Alvar’s earlier actions, and an oracle identifies Lucy as the deciding factor in whether Saul will rule. Alvar consequently argues that Lucy must remain in Axus for the sake of his people. The treaty no longer functions simply as a completed peace settlement; it becomes a continuing state of emergency in which Lucy’s location and identity are treated as matters of collective survival.

Alvar’s public address to Underland makes the treaty’s political stakes visible to the whole population. He announces that Saul is returning and will again try to oppress the people. He also admits that he cannot protect them from the monster Saul controls and that the image of him as an unassailable king is a facade. The peace established under the treaty is therefore inseparable from the credibility of Alvar’s kingship. When that credibility is shaken, the treaty’s promises of protection are shaken with it.

Limits, Inheritance, and Significance

The treaty’s claims are tested against the rival legal orders of Axus. Goblia, under Remora, uses the Star Wheel to tear criminals apart limb by limb before removing the head, while its restored old religious system permits only one female to live in a hive and destroys most female infants unless Remora selects one as a princess. These practices show that Alvar’s promise to protect Earth humans operates within a fragmented world where different rulers retain radically different customs and where peace requires the imposition or recognition of competing laws. The wedding’s public demand for a kiss and its requirement of marital cohabitation likewise demonstrate that local law can determine how the treaty must be performed.

The agreement also reaches beyond Lucy’s marriage into future succession. Sola Brightfeather explains that once Lucy and Alvar’s heir reaches twenty-five, the Underland Council will judge whether the heir is worthy to succeed Alvar. She supports Alvar’s restoration, noting that he ruled for years without using his Cursed state to exploit his subjects and that the future offers no reason to reject him as king. The treaty thus contributes to a dynastic structure in which peace between worlds may be reproduced through descendants, while the legitimacy of those descendants remains subject to institutional judgment.

At its most idealistic, the treaty expresses Alvar’s belief that Earth and Axus should remain distinct rather than allowing the Bridge to change the course of both worlds. He tells Lucy that Earth belongs to humans and Axus belongs to its own peoples, and that a family carrying Earth-human blood could keep both worlds safe forever. This vision reframes the marriage as a boundary-preserving alliance rather than a project of conquest. Yet the treaty’s actual operation remains deeply ambivalent. It protects Earth by placing Lucy under royal authority, promises care while authorizing her removal, and seeks consent from worlds by beginning with a promise made before its central subject was born. Its enduring significance lies in that contradiction: peace is achieved not by eliminating coercion, but by concentrating diplomatic responsibility, legal protection, dynastic expectation, and political danger in Lucy Hammond’s life.
