Shadow of the Underworld

Episode one sets the caste cruelty of the trial ground. The horn calls for men, and the nobles tell the half-breed slave he is not even fit to sign his own name, promising he will one day kneel and swallow his words. The crowd assumes a slave or two dying in the trial will go unnoticed. His mother takes the beatings as part of life, then hands him his father's thing to carry into the night trial; he worries he will be laughed off the field, and asks again who his father was. When he answers a mocking noble that at least what he carries is his own, the legacy item reacts to his blood.

Episode six moves to a secret night meeting. The slave notes his enemies do not dare kill him in the open and work through hidden means instead. Lana comes alone and tends his wound with a soulstone remedy, warning that Valden will go for the kill in tomorrow's duel and that Cassius has already handed over the plan. They examine the broken pickaxe, which she recognizes from old texts as no ordinary tool; he says it has waited for him, as if it already knew him, for as long as he can remember.

Episode four brings Lana, Lord Vox's daughter, into open conflict with her betrothed Cassius, who cannot understand why she helps a slave in public. She answers that who she touches is none of his concern, because they are not married yet. The slave says he has never made a single choice for himself in his life, then decides to try insolence himself. The authority keeps him on for the second trial: awaken the underworld state, and fail and he dies on the spot for blasphemy; no mortal has roused it in a thousand years.

The Half-Breed Slave, Lana and Cassius carry the opening arc.

The Half-Breed Slave

The underdog who carries his father's legacy into the trials

Dirty, guarded, and long used to beatings, he enters the night trial with the broken pickaxe his father left behind rather than a noble's arms. He has spent his life with no choice of his own, and the trial is the first place he dares answer the mocks and claim what is his.

Lana

Lord Vox's daughter who defies her betrothal to help him

Raised inside a noble house and promised to Cassius, Lana steps between the slave and the public humiliation of the trial field. She sneaks away at night to tend his wound and warns him about the planned duel, the one person who makes him feel he might fight back against his arranged life.

“"I've never made a single choice for myself in my life." — episode 4”

Cassius
