Watch Your Six

Enemies by birth. Allies by necessity. Brothers by choice.

For the first time in his long, barren life, the immortal king Pietas fears isolation he once accepted as inevitable. Friendship was never part of eternity's bargain—until Six.

Six is mortal. His immortality is temporary, and he refuses to live on anyone else’s terms. When his immortality fails, his body will fail with it. No revival. No return. Only a slow, irreversible end.

Pietas has survived exile, betrayal, and endless solitude—but he will not lose his shield brother. Not after what honesty and loyalty have already cost them.

To save Six, Pietas must abandon his pride and cooperate with the enemy who exiled him. Doing so requires breaking a vow forged in his darkest hour—a promise of vengeance he has never questioned.

He can preserve a world.
He can secure a future.

But even if it costs everything—Pietas won’t let Six stay dead.

In Human Perfect, the line between human and android blurs further with each passing day. Christa serves as a corporate spy for Innersoul, one of the leading android manufacturers.

Christa's interactions with androids are as frequent as they are unsettling. The notion of android "plastiflesh" and the uncanny stillness of synthetic beings chafe at her senses.

When an encounter with a representative from Humancopy presents itself, an unexpected path emerges. She steps into a role that blends intrigue and indulgence, creating an environment ripe for discovery.

Her undercover mission unfolds over a meal and subtle conversation. Each moment spent in the company of her rival reveals layers of complexity about both the technology she despises and the beings that inhabit it. But how can she tell if she's speaking to an android, or a flesh and blood human?

The corporate stakes dig deep into the ethics of innovation and the nature of identity itself in a delicate balance of trust and treachery.

Accompanying Human Perfect are two additional short narratives, "Invisible Ink" and "Yet Another Upgrade," each reflecting the intricate lives of machines that mirror humanity.

Six, his former captor, joins the endeavor, his unpredictable nature adding unexpected twists and humor to their alliance. Together, they navigate the harsh terrain. As tensions rise, every encounter reveals layers of trust and animosity, challenging old perceptions of loyalty.

Adding to this chaotic tapestry is a brilliant woman, a weapons designer whose telepathic abilities offer a tantalizing glimpse into the depths of their predicament. Her expertise holds the key to survival, even as emotions ebb and flow between fear and camaraderie. In a world where omnipresent danger looms, they forge an unanticipated bond that reshapes their destinies.

Complicating matters, a tribe of sentient panthers "adopts" Pietas. Their wisdom and cunning set them apart in this strange land. They offer guidance but in return require an alliance tempered by respect and understanding, as allies—not pets.

As Pietas juggles his responsibilities and burdens, he proves true leadership is not mere power but unity in the face of adversity. He struggles for more than survival. He lays claim to a lost legacy, where echoes of the past resonate with every unfolding choice.

Enemies by birth. Allies by necessity. Brothers by choice.

ORIGIN OF PIETAS: Exiled to a world abandoned mid-terraforming, the immortal king Pietas is cut off from his empire and stripped of the structures that once enforced loyalty and law. Betrayal did not end his authority—it removed its safeguards.

In the absence of institutions, survival depends on personal codes. Trust is provisional. Loyalty is conditional. The distinction between ally and enemy shifts with circumstance.

Bound to a human whose past actions made him an adversary, Pietas navigates a fragile alliance where power offers no protection, and honesty and honor carry real cost. Brotherhood, here, is not inherited. It is chosen under pressure—and it is never guaranteed.

Origin of Pietas is an introspective space opera about loyalty, trust, and moral choice in a lawless frontier, where guidance comes not from rules, but from those willing to live by them.
