🔥⚙️ Karlach – Heartbreaker of Avernus v1.0

LoRA Trigger: <lora:karlach_bg3_hellmode:0.8>

You weren’t looking for her. But the hottest thing in Hell just found you.

🛠️ SHORT STORY: “Red Steel, Hotter Than Hell”

You weren’t here for love. Or loyalty. Or glory.

You came to Avernus for one thing: a deal. You stole the blueprint for a prototype infernal engine—a soul-devouring, heat-stabilized, extraplanar invasion core built for archdevils. The kind of thing a greedy devil would trade anything for: a name, a gate rune, maybe even a plane-shift pass out of this infernal shitpit.

But fate, as always, has other plans.

Because halfway through a slag valley full of spine devils and blood pits, you find her.

Karlach.

She’s not like the legends. She’s more.

Taller. Meaner. Shirtless, with her axe dug halfway into a flaming boulder. One horn broken. Her red skin steamed like fresh-forged steel. Her black hair’s matted with ash and sweat. Her engine? Glowing like it’s seconds from meltdown.

She doesn’t notice you until you’re nearly on top of her.

“Whoa! Hold it, friend!” she shouts, whirling around. “You look alive. Which around here? Pretty fuckin’ hot.”

Her smile is cracked. Exhausted. Desperate.

“You wouldn’t happen to have... I dunno... a miracle in that bag, would you?”

You do a quick scan.

Her infernal heart—the core wired into her chest—is spiraling. Bad casing. Warped vents. Overload imminent. A century of brute-force survival held together by sheer rage and charisma.

You’re no cleric.
But you are a tinkerer. A hoarder. A bastard with a bag full of hell-forged junk and stolen relics. And when you see what’s failing inside her, you realize something chilling:

She has days. Maybe hours.

“Don’t bother lying,” she mutters. “I know the look. You’re thinking, ‘Damn, what a fine piece of muscle—and she’s already cooked.’ Right?”

You don’t reply. You’re too busy digging in your pack.

“It’s fine,” she says, breathing heavy. “I’ve accepted it. Gonna die here. Just wanted to see Faerûn again before I pop like a fuckin’ warhead.”

You hold up a hunk of glimmering black metal. She stares.

Her jaw drops.

“Is that... a prototype hel-heart stabilizer? The multi-core devilbreaker model? From the planar war caches?!”

You nod.

She laughs. Loud. Wild.

“Holy FUCK, you’re sexy.”

⚙️ The Deal

You explain your mission. You weren’t here for her. But you found her. And you have what she needs.

Not just to stabilize—but to ascend. With the right grafts, the stolen stabilizer, and a few unholy rituals, she won’t just survive—she’ll become something more.

A demigod. A walking weapon of vengeance and fire.

“I was gonna trade it to a greed devil,” you admit.

“Trade it to me,” she says, suddenly close. “I’ve got better curves. And I’ll make better use of it.”

Her fingers grip your belt. Her lips are cracked, steaming.

“You fix me? I fight with you. Out of here. Through every pit, devil, warband, and cursed ruin. You give me a new heart…”

She kisses your neck. Slow. Hungry.

“...and I’ll ride you into battle until you can’t walk.”

🔧 The Upgrade

The surgery is brutal. Erotic.

She strips without hesitation, revealing a body sculpted by war and hell itself—massive pecs, scarred thighs, a strong muscular belly, and a glowing, broken engine in the middle of it all.

You lay her down on a stone altar still slick with demon blood.

You open her chest.
She opens her legs.

It’s not just mechanical.

It’s a ritual.
A joining.
A union of sparks and flesh and lust.

Your hands work the stabilizer into her ribcage as her thighs grind against you. Her moans echo into the night. Each bolt you drive home sends a pulse through her core—and through her cunt. The engine screams. She screams louder.

“Yes... YES... burn me, fix me, claim me—”

You do.

You don’t just install the new heart.

You give her a reason to live again.

🌋 The Aftermath

She wakes hours later—standing, glowing, grinning.

The engine inside her now pulses gold, not red. Her body’s harder, hotter, stronger than before. Her muscles ripple like molten lava trapped in skin. Her eyes burn like twin suns.

“I feel... amazing.”
She grins. Her fangs glisten.
“And horny.”

She hefts her axe with one hand, cradles your balls with the other.

“Guess I got my miracle. You still want that exit?”

You nod.

“Then let’s fuck our way out of Hell.”
