Earth

Earth is Lucy Hammond’s birthplace and the originating realm of the treaty that binds her future to Alvar and Underland. Although it first appears to be the familiar world of Lucy’s family, friends, and human life, the novel gradually reveals that Earth is also a vulnerable political territory whose safety depends on diplomacy, the Bridge, and Lucy’s contested identity as the human woman chosen to become Alvar’s queen.

Definition and Political Position

Earth is the human realm set against the supernatural societies of Axus. Its relationship with Axus is formalized through an agreement made under oath to Elias on October 10, 1993, corresponding to the twenty-third day of Havath, 2918, in Axus. The document records an agreement between Hannah Delaney and King Alvar of Underland: Hannah’s unborn daughter is betrothed to Alvar as his future wife and queen in order to secure peace between Earth and the realms of Axus.

The treaty assigns Earth both protection and dependence. Alvar’s authority over the other Axian countries is presented as strong enough that, if he orders them not to attack Earth, they will obey. Hannah explains that some people of Axus are hostile toward humans and that Alvar’s diplomacy prevents his kingdom from attacking or conquering Earth. The arrangement therefore treats Lucy’s marriage not as a private family matter but as a defensive instrument in relations between worlds.

The written agreement also promises that, once Lucy comes of age, Alvar may retrieve Hannah and Lucy to live in Underland. Their material and personal needs are to be provided for, while the Underland Guard offers protection and the Institute of Underland teaches them the customs of their new society. The contract thus turns movement from Earth into a planned political transfer, presenting residence, education, security, and marriage as parts of one cross-realm settlement.

Earth as Lucy’s Origin and Obligation

Lucy’s connection to Earth begins before her birth. Hannah tells her that Lucy was expected to die in the womb and that she promised the unborn child to Alvar if he could save her. Alvar later clarifies that Lucy received an infusion of Cursed blood while still developing as a fetus; this blood gave her unusually rapid healing and made it possible for her to survive. Earth is therefore not merely Lucy’s home but the site where her body was made the living condition of the treaty.

The arrangement places Lucy in a conflict between personal choice and inherited obligation. When she protests that she is already involved with Mike Jones and cannot become Alvar’s bride, Hannah insists that Lucy has been Alvar’s chosen bride for many years. Refusing the agreement, she says, would constitute an insult to Alvar and his people and could mean war between Earth and Axus, a war she believes Earth would lose. The threat transforms Lucy’s supposed romantic decision into a matter of collective survival.

Alvar’s later account gives the treaty a second strategic purpose. He says that he had traveled to Earth while trying to ensure that Saul, the tyrant who had once ruled Axus, could not return. Alvar arranged for Saul to be arrested by Earth authorities, but he knew that the imprisonment could last only so long. By marrying the woman whose life had been saved with his blood, Alvar intended to secure a treaty that would further cut Axus off from Earth. Lucy’s birth and survival consequently become part of a long-term containment plan aimed at preventing Saul from restoring his rule.

The Bridge and the Threat of Invasion

Earth’s connection to Axus is mediated by the Bridge, a passage that Lucy crosses with Alvar on the way to Underland. Inside it, the ordinary physical expectations of Earth disappear: the place has no echo, and its silence makes Lucy feel that she has entered a threatening interval between worlds. Alvar warns her to hold on tightly because anyone lost in the Bridge is lost forever. The crossing makes Earth’s separation from Axus literal while also showing that the separation is fragile and can be traversed under dangerous conditions.

The Bridge gives the treaty practical force. Without a route between realms, Earth and Axus would remain distant; with it, marriage, abduction, diplomacy, rescue, and war can pass from one world into the other. Lucy’s departure from Earth is therefore not a simple change of scenery. It is the crossing of a political threshold through which her private life becomes inseparable from the security of her home world.

Earth’s danger is also measured against the violence of Axian regimes. In Goblia, criminals may be executed on the Star Wheel, where their limbs are pulled off one at a time before their heads. Goblia’s one-female hive system, reinforced by Saul after he installed Remora as queen, includes the destruction of female offspring unless Remora selects one as a successor and the short lives of most male drones. The stog, meanwhile, hid for decades during Saul’s reign because his religion demanded them as sacrifices. These examples explain why Lucy and Alvar treat Saul’s return as a threat extending beyond Underland: the tyrant’s history of enslavement, religious violence, and political manipulation could endanger Earth as well as Axus.

Earth’s Future and Lucy’s Return

Alvar identifies Lucy as the deciding factor in whether Saul will rule again. A reliable oracle has judged that her presence must remain in Axus because the future of its people depends on her. The claim intensifies the treaty’s pressure: Lucy is not only the promised bride who secures peace with Earth, but also the person believed capable of influencing Axus’s succession and Saul’s defeat.

Even after the immediate dangers of Saul and Lord Vessin have shaken her, Lucy refuses to return to Earth simply because it is familiar or safer. She tells Alvar that she cannot go back because he is not there, that she loves him, loves Axus and Underland, wants to see them prosper, and wants to have his children. Her choice does not erase the coercive origins of the treaty, but it changes the meaning of Earth in her arc. The world that once represented home becomes a place she can leave without abandoning her identity, because she has adopted a divided but deliberate belonging between Earth and Underland.

Earth also remains present in the future of the new order. Sola Brightfeather foresees that Lucy and Alvar will have two children, one resembling Lucy and the other resembling Alvar, and the succession rules require their heir to be judged by the council at the age of twenty-five. The future rulers therefore embody the continuing connection between the human realm and the Cursed king’s realm. Earth’s decisive significance lies in this transformation: it begins as the endangered homeland whose peace is purchased through Lucy’s body, and it becomes the origin of a cross-world dynasty capable of reshaping relations between Earth and Axus.
