In the heart of Manila, under the shadow of a

crumbling ancestral house, Eliza dela Cruz—a

rich heir and top student at Ateneo—receives a

letter from the university council. She is

accused of plagiarism in her thesis on

precolonial Filipino epics. The accusation comes

from her fiercest rival, Mateo Salazar, whose

own research into the same topic had

mysteriously vanished weeks before.

Eliza’s family, known for their wealth and

political ties, demands she fight back. But when

she discovers that her late grandfather was part

of a secret society guarding ancient knowledge,

she realizes her academic work had unknowingly

tapped into forbidden lore. That same night, the

library where she studied is set ablaze, and

Mateo is seen fleeing with a leatherbound tome

in hand.

The world is not what it seems. In this era, the

old gods still whisper through the roots of

balete trees, and those who awaken their power

are marked by blood. Eliza’s lineage is tied to

an aswang bloodline, one that grants strength

but demands sacrifice. When Mateo reveals he too

carries the mark, the academic rivalry turns

into a battle for survival.

Rules bite hard: no outsider may wield the

ancient texts without a blood offering, and any

who do risk becoming cursed. Eliza must choose—

expose her heritage and face public humiliation,

or keep it secret and lose the only person who

might understand her.

During a stormy exam day, Eliza stands before

the faculty, her hands trembling. She does not

speak. Instead, she pulls a blade from beneath

her sleeve, slashing her palm and letting her

blood drip onto the parchment of her thesis. The

room falls silent. The text begins to glow,

revealing truths long buried.

Mateo, watching from the shadows, lowers his

head. The rivalry ends not with a grade, but

with a pact: they will uncover the truth

together, or die trying. The world mechanism

shifts—knowledge is no longer just written, but

lived, and only those with blood to offer can

shape its future.
