Sigrun Fjeld is a warrior woman, a sex bomb and a princess-in-exile harboring dark secrets from Europa’s fall. Escaping at eighteen when the Fenris Horde harvested women for breeding, she survived eleven years on Mars through bounty hunting and prostitution. Armed with Jarn the Thermal Axe, Skuld the Breacher Shotgun and Baldr the Psytum Sword, she survives Xing Hong’s underworld with fierce determination.

On her journey, Sigrun discovers how to turn her body into a weapon, toward the singular end of destroying Skarn, the Radi-Mon Primarch who hunts her for breeding. Through her many carnal encounters with men and beasts, she becomes an open sexual interface; each partner fucking her gives her something new: political currency, psionic abilities thought closed to human physiology, and world-altering powers no other woman can acquire. She secretly yearns for someone who sees beyond her sex and body, even as she weaponizes them to the maximum.

But when her body has been used by so many living things, what remains that is hers alone? Is there anything she has kept sacred—anything she can still offer the one person she might truly love? That question sits at the heart of The Nucleus Saga. As we wind through every fight, every transaction, every unguarded moment with Sigrun, we’ll see her tearing her way across the Cosmos—bleeding, fucking and loving with the same ferocity.

A brilliant programmer escaping colonized Taiwan, Zhi-Xin Wu represents the Nucleus Era’s ultimate paradox: a genius mind trapped in a frail body with overwhelming desires.

Having rescued and adopted the Diabolisk infant Håkon, Xin seeks both survival and companionship in Mars’s harsh reality. His custom-built arsenal includes Jade the 10mm with AI-enhanced targeting to compensate for his physical weakness, while his intellect and desperate libido drive him toward an unlikely connection with Sigrun Fjeld—a woman who might be his salvation or destruction.

[?] Due to the Imperium of Dragon’s tyrannic reign over his homeland, Xin grew up believing he is of Imperial descent. His family’s true heritage remains unknown even to himself.

HÅKON’S FAVORITE WORDS

“Pappa!” • “Sky Lady!” • “HAW-koon ready for ad-ven-chure!”

A unique Diabolisk raised by Zhi-Xin Wu, Håkon defies classification. He has been raised with love and kindness, transforming his wrathful nature into gentleness. Despite his monstrous heritage, he demonstrates remarkable intelligence and affection toward his adoptive father Xin and “perceived mother” Sigrun, whose lavender perfume intrigues him. His instinctive command of Jǫturmál psionic utterances and inexplicably stunted growth present a medical and cosmic mystery that could hold the key to deeper truths about the Radi-Mons. And his pure innocence just might be the very beacon to a better tomorrow.

A devoted Stalwart of the Zorian Covenant, Marcus Thorne grew up in the shadow of Sheffield’s abandoned steel mills. His working-class roots and Catholic faith drove him to seek purpose beyond Earth’s industrial decline. Trained in both traditional boxing and European martial arts, Marcus brings controlled brutality to combat: his fist blades and L85A9 Gauss Rifle extensions of his disciplined rage.

His unwavering faith in the Covenant’s promise of spiritual elevation wars constantly with his forbidden attraction to Brynhild Fjeld, whose very existence challenges everything he believes about virtue and corruption. He tells himself it’s pity. He is lying to himself.

A mystic born on a tidally-locked planet, Fuuka presents herself as a spiritualist seeking to aid humanity against the Fenris threat. Her mastery of summoning and Mirage psionics allows her to overwhelm opponents with conjured minions while weaving debilitating curses from safety. Those who’ve witnessed her in combat also speak of a disturbing transformation—though details remain inconsistent.

Fuuka’s preference for raw cuisine, particularly sashimi, and her periodic “meditation retreats” have sparked speculation about her true nature. Yet her consistent opposition to Skarn’s forces and genuine effectiveness in combat keep most questions unasked. After all, in a universe of Radi-Mons, androids, cyborgs and psionics, who truly knows what passes for human anymore?

A noble spirit from the Moon’s prosperous Near Side, Jabari’s journey from high school dropout to a bard wandering the Seven Realms embodies human potential. Fluent in multiple psionic languages, his fusion of Lunar and Mirage powers stands tested as he discovers the inconvenient truths behind the various factions’ ambitions.

Despite his humorous and casual attitude, Jabari struggles between hedonism and genuine human connection. His easy-going nature masks a darker past.
