The Underworld did not try to stop Cynthia when she turned away from the palace.
That frightened her more than pursuit.
The tunnels stretched endlessly, carved from black stone veined with faint, cold light. No guards followed. No monsters challenged her. It was as if the realm itself was watching—measuring.
Her borrowed shoes lay discarded behind her, their wings twitching weakly before going still. She did not look back.
Almost lost, she thought.
Not to Tartarus.
To inevitability.
She moved carefully, every step deliberate. The air was thin here, heavy with memory—whispers clinging to the walls like frost. Regrets. Names spoken too late. Promises never kept.
Cynthia breathed through it.
She had learned young how to endure silence.
A sound reached her—padding footsteps.
She froze, knife half-drawn.
A shadow emerged from the dark: three heads, massive shoulders, eyes glowing dim amber.
Cerberus.
He did not growl.
He sniffed the air, tails swaying uncertainly. One head whimpered—soft, almost confused.
"It's okay," Cynthia said quietly, lowering her blade.
Her voice didn't echo here. It settled.
She crouched, careful not to stare, not to challenge. The beast's massive paw scraped stone as he leaned closer, breath warm, curious.
"You're just doing your job," she murmured. "So am I."
One head nudged her shoulder, gently. Another sneezed.
She smiled—small, surprised—and scratched behind a heavy ear.
The ground trembled faintly.
Far away.
Something like thunder.
Cerberus stilled, ears lifting. His heads turned—not toward Cynthia, but upward, as if sensing a clash beyond his realm.
Cynthia felt it too.
A pull in her chest. Salt and iron. Fury and resolve.
Percy, she thought.
Cerberus stepped aside.
The path beyond him opened, narrow but clear.
"Thank you," she whispered.
The beast huffed, almost proud.
She continued on.
The way grew steeper, colder. Stone gave way to roots pushing down from the living world above, pale and stubborn. Life intruding where it did not belong.
Cynthia climbed.
Her hands bled. Her muscles burned. More than once, she nearly slipped—but each time, she found purchase where none should have been. A branch bent instead of breaking. A foothold appeared just as she needed it.
She did not question it.
She had learned not to.
At one point, exhaustion forced her to rest. She pressed her forehead to the stone and closed her eyes.
For a moment—just a moment—she imagined moonlight. Cool and steady. Not bright, not warm. Watching, not interfering.
Not judging.
She stood again.
When she finally broke through—gasping, lungs screaming, hands clawing at soil—the sky above was pale with dawn.
The living world.
Cynthia lay there for a long time, staring upward, chest rising and falling, feeling the weight of the Underworld loosen its grip.
She was still unclaimed.
Still unseen.
But not alone.
Somewhere far away, a god of war was licking his wounds.
And somewhere between shadow and starlight, something ancient had noticed her—and chosen, for now, to remain silent.
