At the top of the illustration image: *Happy Birth-Day, Maik — May the Emperor forgive the cake heresy!*

Prompt for image:  
An illustrated, comedic scene featuring grimdark Warhammer 40k Dark Angels Space Marines standing solemnly in full power armor — except instead of bolters, they're awkwardly holding party balloons and slices of birthday cake. One particularly serious-looking Dark Angel is lighting candles on a Chaos-star-shaped birthday cake with a plasma torch. Confetti gently falls like ash on a war-torn battlefield in the background. In the corner, a tiny cherub servitor with party hat and noisemaker floats serenely, blowing streamers while a purity seal dangles from the string. The mood is comically epic — a ridiculous fusion of ominous grimdark intensity and festive birthday chaos.

Create a humorous birthday-themed scene set in a fantasy universe known for its grim ambiance. Depict a majestic figure, traditionally stern, blowing out candles on a huge, intricately decorated cake, his face beaming with an unusual smile. Beside him stands a loyal armored knight, comically attempting to burst an overflowing piñata with his heavy-duty firearm, with candy and confetti bouncing off his strong suit of armor.

Imagine a room bustling with joy. In the middle, a table gets some unique decor; it carries a birthday theme blended with elements from an intense grimdark galaxy, reminiscent of mythical far-future battlegrounds. A lifelike diorama representing a notorious warrior faction's battlefield takes center stage, with trenches filled with crimson frosting symbolizing the blood of enemies. Small figurines possess strange features as if touched by chaos forces - each topped with party hats for a hilariously ironic touch. Above all this hangs a Chainsword-shaped piñata, ready for its impending 'execution'. Hovering blood-colored balloons enliven the martial scene, orchestrating a playful atmosphere amid the treats.

A humorous 30th birthday card design set in the grimdark sci-fi universe resembling the one in unique tabletop games. It features a central figure named Vinny, dressed in vibrant and oversized alien carapace armor, holding a large, festively wrapped gift that wriggles with the essence of grotesque creatures of decay. The backdrop is a birthday party lopsided midst the grimdark environment, with alien and decay-themed balloons and streamers. In all this chaos, a mischievous tiny demon-like creature pops out of a birthday cake.

**Image Prompt:**

At the top of the cartoon image, “Shaotong, for the Emperor’s birthday cake — PURGE the calories!”

A cartoon-style image featuring a group of overly enthusiastic Space Marines in lilac-painted armor charging into a surprise birthday party. One Marine holds an oversized, comically elaborate birthday cake shaped like a chaos skull, while another brandishes a party popper like a plasma gun. Balloons float in the air emblazoned with purity seals, and a dreadnought in the background wears a birthday hat, solemnly holding a balloon that says “+1 to Age.” A servo-skull hovers nearby carrying confetti. The whole scene is celebratory but absolutely ridiculous in classic grimdark-meets-slapstick fashion. The color scheme includes various shades of lilac mixed with party pastels for contrast.

At the top of the image, "Brother, even the Emperor couldn't foresee this many candles!"  

- The image is a realistic, dramatic photograph of a grimdark war-torn battlefield on an alien planet at twilight.  
- Standing proudly in the center is a grizzled, larger-than-life Dark Angel Space Marine—hulking, fully armored, with his helmet off to reveal a comically tired expression and party hat strapped awkwardly to his head.  
- His plasma gun is slung over one shoulder, while the other hand is holding an oversized birthday cupcake, with way too many candles erupting in a minor plasma explosion.  
- In the smoky background, fellow marines awkwardly gather around a giant “Happy Birthday, Brother!” banner held up by servo-skulls, while chaos daemons look confused and mildly offended.  
- One corner of the image features a gift box clearly labeled "Purity Seal Stickers (Gluten-Free!)"  
- Overall mood: epicly grimdark meets hilarious birthday chaos.

At the top of the image, "Brother, even the Emperor couldn’t purge your birthday cake fast enough!"

– Create a realistic photograph-style image of a towering, battle-worn Dark Angels Space Marine, in full gothic green and bone-white power armor, seated at a hilariously tiny birthday party table. The table is adorned with an absurdly small birthday cake topped with a flickering candle and confetti that clashes with his grim demeanor. One massive armored gauntlet delicately attempts to hold a paper party hat in place, while a servo-skull floats nearby, struggling to blow up balloons. In the background, other brooding battle brothers reluctantly hold up a “HAPPY BIRTHDAY, BROTHER” banner, clearly annoyed that this counts as a mandatory squad morale event. The setting is a gothic cathedral spaceship interior, but with subtle birthday party chaos clashing against the grimdark atmosphere.

**Image Prompt:**  
At the top of the realistic photograph image: *"Happy Birthday, Brother – For the Emperor... and cake!"*

A hyper-realistic photograph-style image depicting a towering, grim-looking Dark Angel Space Marine in full battle-worn power armor standing stoically in a chaotic battlefield—but instead of a chainsword or bolter, he’s dramatically holding up an absurdly tiny, pink birthday cupcake with a single lit candle. Confetti gently rains from the smoke-filled sky behind him. In the background, other Space Marines look on confused, some wearing cheap party hats awkwardly balanced on their helmets. One Marine in the corner is begrudgingly blowing a party horn. Alien enemies flee in the distance, terrified by the celebratory chaos. The mood is dead-serious but absurdly funny in contrast—grimdark meets birthday cheer.

At the top of the image, "Even the Emperor can't protect you from this many candles..."

- Create a realistic photograph-style scene featuring a Warhammer-inspired setting: an epic, cathedral-like banquet hall dimly lit by flickering torches and glowing purity seals.
- At the center, Saint Celestine (Warhammer’s angelic warrior saint), clad in gleaming golden armor, descends dramatically from the heavens—her wings outstretched—carrying an enormous, slightly burnt birthday cake with sparking candles sticking out like battlefield flares.
- Surrounding her are confused and slightly alarmed Space Marines awkwardly trying to blow out the flames with servo-fans.
- One Imperial Guardsman in the background holds a sign reading "How many millennia young now?"

At the bottom of the image, "Your birthday is truly... grimdark and glorious!"

- Create a hilarious Warhammer 40K-inspired illustration showing a squad of Dark Angels Space Marines in full ornate power armor, cautiously surrounding an enormous, flaming birthday cake like it's a chaos relic.  
- One marine is holding a melta gun aimed at the cake for “extra help” with lighting.  
- Another is scanning it with a purity seal in hand, and a Chaplain is chanting over it suspiciously.  
- In the background, a nervous servitor rolls up a "Happy Birthday" banner, while a servo-skull hovers by with a party hat awkwardly balanced on it.  
- The overall tone is comically epic and overly dramatic—because every birthday for a true Dark Angel is a grimdark celebration.

At the top of the realistic photograph image: "Happy Nurgle-Day, Daniel – May your decay be delightfully birthday-festive!"

**Prompt:**  
A highly detailed, realistic photograph-style image of a birthday party scene inside a grimy, rust-covered Death Guard battleship. A towering, grinning Plague Marine in full power armor, splattered with ichor and covered in pox-ridden fungi, is cheerfully blowing into a party blower. He wears a birthday hat that's hilariously too small for his helmet. Nearby, Nurglings are gleefully tossing infected confetti into the air and one is bringing a lumpy, mold-covered birthday cake shaped like a Nurgle symbol, complete with lit, ooze-dripping candles. In the background, there’s a banner made of rotting flesh that says “HAPPY NURGLE-DAY, DANIEL” strung between two corroded pillars. The whole scene is both gross and oddly festive – a grimdark celebration bursting with plague-fueled cheer.

At the top of the image, "Maik, even the Dark Angels paused their hunt for The Fallen to wish you a Loyalist-level birthday!"

- Illustrate a comically epic scene featuring a squad of Warhammer 40K Dark Angels Space Marines in their grim, gothic armor — but instead of bolters, they're holding balloons and party poppers.  
- One is awkwardly balancing a birthday cake on a servo-arm, while another looks confused holding a wrapped present labeled "Definitely not chaos... probably."  
- In the background, the imposing Chapter Master grimaces stoically while wearing a party hat that says “I came for redemption, stayed for the cake.”  
- Add touches of grimdark décor—banners reading "FOR THE EMPEROR’S BIRTHDAY" and gothic gargoyles hanging streamers.  
- Overall tone: moody yet ridiculous, like if Grim Reapers were terrible at throwing surprise parties.

At the top of the image, "Daniel, Nurgle granted you immortality... just so you could keep having birthdays that smell worse than his Plague Marines!"

– Depict a highly detailed, realistic photograph of a weathered Warhammer 40k Death Guard squad in full plague-ridden power armor, standing proudly in a dimly lit birthday party setting.

– The scene should contrast grimdark Warhammer aesthetics with cheeky party details: rotting streamers, a mutated balloon shaped like a “40,” pustule-covered cupcakes on a rusty cake stand, and a Plague Marine attempting to blow a party horn that's oozing slime.

– In the background, add a partially mutated Nurgling holding a saggy birthday banner that reads "Decay Another Year Wiser!" while joyfully popping out of a gift box.

– Light should fall dramatically on the "cake," which is actually a bubbling vat of Nurgle sludge topped with a single flaming candle.

- Illustrate a humorous, cartoon-style Warhammer 40k scene featuring a squad of overly serious Dark Angels in full grimdark armor, standing dramatically around a hilariously massive birthday cake shaped like a drop pod.
- One of the Space Marines awkwardly holds a party hat, unsure of whether it violates the Codex Astartes.
- Another is reluctantly blowing a streamer, clearly battling his inner shame.
- Servo-skulls float above holding banners that read “Heresy-Free Since Your Last Birthday!”
- Confetti rains down in the style of a chaos incursion—only, it’s glitter.  
- In the background, a fallen chaos marine peeks in sadly from a corner with a “No cake for traitors” sign above him.

At the top of the Watercolor Style image, "Happy Birthday Dena" hand-lettered in jagged, bone-white strokes with subtle watercolor bleeds.

A soft, moody watercolor scene of Warhammer ghouls throwing a grimdark birthday bash: a hunched pack of gaunt, pallid ghouls crowd around a lopsided skull-shaped cake bristling with crooked candles, wax dribbling in buttery blooms. They wear torn, ridiculous party hats; one gnaws a femur like a fork, another clutches a cracked goblet, and a third leers over the cake, drooling with comic menace. Gothic ruins and a sickly moon wash the background in bruised purples and cold teal; warm candle-gold splashes across their bony faces. Employ soft watercolor washes with delicate gradients, wet-on-wet edges, subtle pigment blooms, and visible natural paper texture; keep lines loose and splattery, with crisp accents only on eyes, teeth, and claws. Palette: pallid greens, ashen grays, bruised violet, candle amber. Make it cheeky, darkly funny, tastefully grotesque (no heavy gore), image-dominant with airy negative space around the title.

At the bottom, in a small, messy ink caption: "Have a ghoul day—now eat the bloody cake."
