Cover reveal! Elysium’s destruction looms; its greatest pilot Persephone is being eaten from within. She stands to become either a god—or a monster. Our mecha Greek myth retelling continues. More cannibalism, more lesbianism!

A woman with long white hair covers one eye with her gloved hand; her other eye is glowing and red with a crosshair-shaped pupil; streaks of blood run down her face. She wears a black pilot’s suit with gold accents against a yellow and black background. Book title: The Persephone Effect.

In times of crisis, sisterhood keeps us together 🫡
An illustration showing three figures standing over a table with a futuristic looking map. On the left, pointing at the map, is a young woman in a red windbreaker jacket - very emergency management chic. She has short brown hair and is wearing a cap that matches her jacket. In the middle is Zeus, King of Olympus. She has radiant gold skin, luscious blonde hair, and is wearing a gold button up shirt with her tits out (pretty much). To her right is Hades, dressed in a militaristic black shirt with gold trim, her black hair in a bun.

Hepaestus, Brass Consort

#gunmetalolympus
Hephaestus from the Hades Calculus, appearing redheaded and made of highly reflective brass, wearing a white sherwani with a bright red cloth draped over zer shoulder. The cloth is patterned with golden cypress leaves, its hem lined by golden scales stamped with zer hammer. Over zer chest hangs a red-and-gold beaded necklace. Ze looks quite dapper.

And a slightly cheated study from Jurassic Park.
A study of Ellie Sattler in Jurassic Park redone as Persephone with a bit of extra blood.

So, it's Persephone Day today, right?
Time to post all my Persephone art.
Meme redraw about trans girls turning into their mothers, but it's Persephone and Demeter from Gunmetal Olympus. Persephone getting harassed by some of my OCs, the genetically engineered evil faction from Ceres that think she basically counts as one of them. A crossover with my Harem Protagonist Series with the HC gods reduced from being tied to mecha to being tied to power armour O'tmyil in Harem Protagonist. Hades is not impressed, but Persephone likes it being rather hands on. She's disappointed by the lack of bloodshed, which Svetlana explains is because the series is PG-13. Which is news to adorable vampire girl Thisbe who is covered in blood. Persephone meeting Glass from Inhibitor Phase, where Persephone finds out that Glass was healed with bits of her friend Warren, and now he's just stable as a headmate, which ticks Persephone off.

I am so hyped for today's release, have a Dread Persephone

#gunmetalolympus
rough digital painting of Persephone Go. Her body is red, hair white, against a dark blue background. She has a halo of cool light behind her head. She looks down and over the shoulder at the viewer, with a glint of golden light in her eye.

Have a really silly trans meme redrawn as Hades Calculus.
A trans meme about transitioning turning a trans girl into her mother, but it's made Persephone and Demeter. Demeter has been portrayed with white hair to make the similarities stronger. Persephone's handle on 'Z.com' is @cgirlswagg instead of @tgirlswagg, since she's cis, but in a rather trans way.
