House Loyalties

Lore & Background

The Society organizes humanity into a strict caste system where Golds rule as the mentally and physically superior elite. Within this ruling class, twelve Great Houses dominate the Institute and the political landscape of Mars. During the Institute, students are drafted into these Houses to compete for dominance in a massive recreation of medieval warfare within Valles Marineris. Each House is assigned a castle and must conquer others using a system where capturing an enemy's standard allows them to enslave opposing students, forcing them to obey commands. The internal culture of each House is defined by its specific leadership: House Mars, led initially by the bloodthirsty Titus au Ladros, fractures into factions before Darrow manipulates alliances to seize control. Other major players include House Minerva under Virginia "Mustang" au Augustus and House Pluto led by Adrius "The Jackal" au Augustus. The Proctors, such as Fitchner au Barca of House Mars, oversee these conflicts, though they are sometimes bribed by figures like Nero to rig outcomes in favor of specific students.

In Their Own Story

The Institute on Mars transforms the landscape into a brutal theater of war where House Loyalty is tested through blood and strategy. Darrow, posing as a Gold named "Darrow au Andromedus," enters House Mars alongside his friend Cassius du Bellona. The conflict begins immediately during the Passage, where students pair off to fight barehanded; Darrow kills Cassius's brother, Julian, planting the seeds of future betrayal. As the war expands across Valles Marineris, Titus au Ladros rapes enslaved peers from other Houses, causing House Mars to fracture. Darrow manipulates House Minerva, led by Mustang, into defeating Titus's faction, eventually becoming the leader of House Mars himself. The turning point arrives when Titus is revealed as a transformed Red; to maintain his cover, Darrow sentences him to death, and Cassius executes him. Later, rumors reveal House Pluto is led by "the Jackal," Nero's son. Darrow outwits rival Houses but chooses to let Mustang escape rather than killing her. When the Jackal reveals Darrow killed Julian via video, an enraged Cassius duels Darrow, stabbing him and usurping control of House Mars. Mustang rescues the wounded Darrow in a forest cave, where they develop romantic feelings while he recovers.

Reader's Guide

Navigating House Loyalty requires understanding that it is both a survival mechanism and a trap within the Society's structure. For Golds, success is measured by conquering other Houses during the Institute or gaining favor with the Sovereign on Luna. The system rewards ruthless ambition, as seen when Darrow traps The Jackal, who amputates his own hand to escape, only for Proctors to intervene and kidnap Mustang. To win one must master the rules of enslavement: capturing a House's standard forces opposing students to obey. However, loyalty is fragile; Fitchner reveals Nero bribes Proctors to ensure The Jackal wins, exposing the corruption beneath the surface. Darrow's strategy involves freeing slaves from captured Houses to amass an army, eventually conquering Houses Ceres and Apollo. The ultimate test of loyalty occurs when Mustang discovers she is The Jackal's twin sister; despite her lineage, she dutifully delivers him to Darrow, allowing House Mars to conquer all others and win the Institute title. Yet, even victory brings new chains: Nero Augustus offers Darrow a position as his Lancer if he hides the rigging of the games, forcing Darrow to publicly join House Augustus despite his hatred for the man who killed his wife.
