Chapter Thirteen: Threads of the Abyss

For the first time in what felt like forever, Sera did not dine alone in the vast, shadowed expanse of the Great Hall.

Sitting across from her at the long, polished stone table was Kaelen. The floating starlight lanterns cast warm, golden hues over his sharp, carved features, softening his usually cold silhouette. Freshly baked bread, sweet fruits, and steaming herbal tea sat between them, but the real feast was the quiet, unspoken tension lingering in the air.

Sera took a small sip of her tea, resting her chin in her palm as she looked at him. "So... First Blade of the High Realms," she started, trying to sound casually curious. "What does an ancient warrior angel actually do when he's not fighting demons or dragged along by a mortal?"

Kaelen paused, his long, leather clad fingers resting on his silver goblet. His storm-grey eyes flicked up to meet hers.

"I maintain order," Kaelen answered neutrally, his tone even and controlled. "I enforce the law of the High Citadel."

Sera leaned in a bit closer, refusing to give up easily. "Okay... but what about you? Do you have hobbies? Do angels just stand around in pristine armor waiting for war? How was your life before all of this?"

A faint, almost imperceptible twitch touched the corner of Kaelen’s jaw. He was weighing every single word, answering in brief, guarded sentences. As a high ranking celestial commander, there were laws, ancient secrets, and divine truths that a mortal vessel simply was not permitted to know.

"I train. I patrol the frontier borders. That is all," Kaelen said smoothly, shifting his posture. He wasn't about to drop his guard entirely, but he subtly turned the table back on her. "And what of the mortals you left behind? The ones cluttering your thoughts in the training room?"

Sera blinked, a faint flush touching her cheeks. "Oh. Mark and Maya?"

"The firefighter," Kaelen specified, his voice dropping into a low, quiet rumble as his eyes narrowed ever so slightly. "The one who frequented your cafe under the pretense of buying coffee he clearly did not need. He had affection for you."

Sera let out a soft, nervous laugh. "Mark? I mean... maybe a little. He was nice. He always tried to make me laugh when work was chaotic. And Maya was my best friend—we used to dream about traveling the world once we saved enough money."

Kaelen listened quietly, his sharp gaze reading every subtle shift in her expression. He intentionally guided the conversation around those mundane, earthly memories, deliberately avoiding the name that he knew bled her heart dry—Celi. He wanted to spare her the pain, to keep the dark clouds from settling back over her eyes.

But Sera wasn't dodging it. The memory of her nightmare was still a raw, throbbing wound.

"Kaelen," Sera said softly, her smile fading as she looked down at her hands tightly gripping her tea cup. "Is it possible... that Celi is actually alive?"

Kaelen froze, his hand tightening around his goblet.

"My nightmare," Sera continued, her voice trembling slightly as she looked up into his intense grey eyes. "What if it wasn't just a dream? What if Celi’s soul isn't gone, but trapped in the Underworld? If she's down there... can I save her? Can we go down there, bring her to the High Realms, or even bring her back to Earth?"

The heavy silence of the Great Hall returned, suffocating and vast. Kaelen set his goblet down, his expression darkening into a deep, calculating frown.

"It is... theoretically possible," Kaelen admitted slowly, his voice laced with heavy caution. "A soul bound by dark abyssal magic can be held captive rather than destroyed. But the Underworld is not a realm you can simply walk into, Sera."

"Why not? You're the First Blade!"

"Because every ruler, demon, and creature in the Underworld is my enemy," Kaelen said firmly, leaning forward across the table. His terrifying, divine aura flared subtly, wrapping around them like a protective shield. "If I step foot into the abyssal depths, it would ignite a full scale realm war. And for a mortal like you? The ambient heat and dark corruption alone would wither your physical vessel in minutes. A mortal cannot survive down there without dark protection, you would need the blood or passage of a high-ranking demon just to cross the Underworld's threshold."

He reached out, his massive, warm hand resting over hers on the table, his storm-grey eyes locking onto hers with an unyielding intensity.

"Do not let desperate hope drive you into the mouth of the abyss, Sera," Kaelen warned softly, his thumb gently brushing her knuckles. "Focus on your training. Focus on surviving. We must face what is in front of us first."

After their meal, Kaelen walked Sera back to her bedchamber. The heavy silence between them felt a little lighter than before, but the weight of their conversation still lingered in the air.

"I must return to the High Citadel," Kaelen said softly as they reached her doors. "I have matters to discuss with Archon Sariel and the border commanders regarding Malakor's movements."

Sera nodded gently. "Be careful."

Kaelen gave her one last, intense look before turning on his heel, his dark cape sweeping through the corridor as he vanished into the shadows of the fortress.

Left alone, Sera stepped into her room and walked straight to the high, arched window overlooking the boundless expanse of the High Realms. Her mind was in complete turmoil, swirling continuously around one person—Celi.

If Celi's soul was really trapped down in the Underworld... did that mean she had to summon a demon? The thought sent a cold, terrifying shiver down her spine. That's insane, she thought, leaning her forehead against the cool glass. All this time, she had assumed that summoning Kaelen—an archangel—would give her the power to go anywhere, even into the dark depths to save her sister. But she was wrong. An angel couldn't freely tread into the abyssal fire without starting a catastrophic realm war.

Should I have summoned a demon instead?

Sera gasped, quickly shaking her head in horror at her own dark thoughts. No, no! What am I thinking?! Erase, erase! That's crazy!

Exhausted by her own spiraling mind, Sera dragged herself over to the canopy bed, collapsed onto the soft sheets, and pulled the covers over her shoulders. Within minutes, her heavy eyelids gave out, and she drifted off to sleep.

The dream returned, but it was far darker this time.

Sera opened her eyes to a grand, twisted hall made of jagged black obsidian and burning hellfire. Sitting upon a towering, terrifying throne of skulls was a creature of intense, suffocating presence—Archduke Azazel, one of the most powerful and ruthless lords of the Underworld.

Azazel was breathtakingly dark and handsome, possessing sharp, carved features, pitch-black eyes that sucked in the light, and massive, midnight black wings folded behind his back. He wore blood red velvet robes that draped loosely over his broad frame, radiating an overwhelming aura of pure corruption.

And sitting right beside him, lounging on the armrest of his throne, was Celi.

Sera’s breath caught in her throat. "Celi...?"

What was this? Was Celi... a demon's lover?!

Celi slowly turned her head toward Sera, but she no longer looked like the sweet, innocent sister Sera had loved. Celi's eyes were stark, glowing white hollow and void of humanity. Emerging from her back were a pair of small, dark black wings. She was wearing a skimpy, deep crimson dress that revealed almost all of her skin, leaving almost nothing to the imagination.

"Why didn't you save me, Sera?" Celi's voice echoed through the dark hall, warped and laced with cruel venom.

"Celi, no! Please!" Sera sobbed, tears streaming down her face as she reached out with trembling hands. "I tried! I swear I tried! I was standing right there—"

"You let me die!" Celi spat coldly, leaning against Archduke Azazel, who offered a dark, mocking smirk. "You failed me, sister. You saved a stranger's soul, but you left me to rot in the dark. I hate you."

"No!" Sera gasped, violently sitting up in her bed, her heart pounding against her ribs like a sledgehammer.

A cold, eerie chill hung heavy in the air. Sera pressed a trembling hand against her burning forehead, her breathing ragged as tears threatened to spill over her lashes. She knew in her heart that the creature in the dream wasn't really her sister... but the words still slashed straight through her soul.

Knock, knock.

Sera flinched, snapping her gaze toward the door. "W-Who is it?"

The heavy oak doors creaked open, and Elara entered quietly, carrying a silver tray with a steaming porcelain cup of herbal tea.

"I sensed your pulse racing from the corridor, mortal," Elara said in her usual cool, neutral tone as she set the tray on the side table. "Drink this. It will soothe your vessel's nervous system."

Sera took the warm cup, her fingers still shaking slightly. She took a small sip before looking up at the stoic servant angel.

"Elara... can I ask you something?" Sera whispered, her voice raw. "What do you know about the Underworld?"

Elara paused, her alabaster face unreadable. "It is a realm of absolute chaos and dark corruption, ruled by the Lords of the Abyss. It is the dark mirror to the Aether. Where the High Realms exist in order and divine light, the Underworld thrives on shadow, deceit, and wild power. Mortals who stray into its depths are instantly consumed—their souls broken and repurposed to serve the High Demons."

A heavy knot formed in Sera's stomach. "And... Archduke Azazel?"

Elara's brow furrowed subtly, a rare flicker of caution crossing her features. "He is one of the ancient rulers of the dark depths. Cruel, magnetic, and immensely dangerous. Why do you ask of such terrible things?"

"Just... bad dreams," Sera murmured softly, staring down into her tea.

Elara offered a brief, polite bow. "Rest your mind, Sera. You are safe within Commander Kaelen's walls." With that, she turned and left the room, closing the doors behind her.

Unable to stay trapped inside the suffocating walls of her bedchamber, Sera wrapped a warm robe over her clothes and stepped out into the corridors. She walked until she found a set of glass doors leading out to the rear of Kaelen's dark fortress.

When she pushed the doors open, her breath caught.

Stretching out before her was a vast, breathtaking garden high above the clouds. A majestic crystal fountain sat in the absolute center, cascading glowing turquoise water over shimmering silver stones. Flowers of vibrant, unnatural colors deep violet, radiant gold, and shimmering crimson bloomed beneath the soft starlight. Elegant stone benches were nestled among the glowing plants, lit by tiny, floating spirit lights.

I'm really in Heaven... Sera thought, stepping out onto the soft, luminescent grass.

She walked over to a quiet stone bench near the edge of the garden and sat down, pulling her legs up and wrapping her arms around her knees. She tilted her head back and stared up at the twin moons glowing brightly against the deep indigo sky.

The Aether. The Underworld. Angels and demons. A month ago, she thought these things were just myths, fairy tales, and stories written in fantasy books. And now, her very soul was tied to an immortal Angel.

Sera closed her eyes, letting the cool, gentle breeze ruffle her damp hair and brush softly against her skin, washing away the lingering terror of her nightmare.

"The night air in the High Realms can be harsh on a mortal."

Sera gasped, jumping violently on the stone bench as the deep, dark velvet voice rumbled right behind her.

She spun around and found Kaelen standing just a few feet away under the starlight.

Kaelen stepped closer, stopping a short distance away from where she sat. His great sword hung loosely at his waist, its pommel catching the soft, ethereal glow of the garden’s floating lights.

"I have returned from the Citadel," Kaelen spoke, his low voice breaking the quiet stillness. "Archon Sariel has scoured the ethereal threads, but the Underworld’s sigils are dormant. We have no news of the eleventh sacrifice... nor do we know when or where Duke Malakor will strike next."

Sera looked up, her brow furrowing slightly as the realization sank in. A quiet, unpredictable grace period—yet shadowed by constant uncertainty.

Kaelen’s storm-grey eyes locked onto hers with a quiet, assessing intensity. "Given the stillness of our enemies... would you wish to return to Earth for a time? To Blackwood Bay, where you were born?"

Sera’s breath caught in her throat. Her eyes widened in utter disbelief. "Wait—really? I can go back home?"

"You may," Kaelen replied smoothly. "However, you will not step foot on mortal soil without me. My presence is required for your protection."

A sudden, genuine wave of joy washed over Sera, the heavy knot in her chest loosening for the first time in days. "Yes! Absolutely, yes!"

"We depart tomorrow at dusk," Kaelen stated, his tone shifting back to its usual disciplined authority. "Which means you will spend tomorrow morning in the courtyard with Vaelin. You must keep your sharp edge, and then rest your body before we cross the veil."

True to her word, Sera pushed through her morning training session with everything she had, earning even a faint nod of approval from Vaelin. She took a brief rest afterward, and before she knew it, Kaelen stood beside her, wrapping his dark, divine magic around them both as they stepped through the celestial rift.

When the blinding light faded, the cool, pristine air of the Aether was replaced by the familiar, damp smell of sea salt, rain, and asphalt.

Sera found herself standing right in front of the familiar wooden door of her old apartment in Blackwood Bay. A sudden, sharp ache pierced her heart—this was the very place where her life had fractured, where Celi had been taken.

She swallowed hard, pulled out her spare key from under the floor mat, and unlocked the door.

Kaelen glided in behind her, his tall, broad frame instantly making the modest apartment feel tiny. His sharp, storm-grey eyes scanned every inch of the room with a mix of warrior vigilance and quiet fascination.

He paused in front of the living room wall, staring intently at the framed photographs pinned up—pictures of Sera and Celi laughing at the beach, awkward childhood birthday parties, and silly polaroids. He then turned to look at the large, black glass rectangle mounted on the wall.

"What manner of scrying mirror is this?" Kaelen asked, pointing a long, leather-clad finger toward the television.

Sera couldn't help the small laugh that escaped her lips. "It's a TV, Kaelen. It plays movies and news. No magic involved."

"Fascinating... yet utterly unnecessary," he rumbled stoically.

"Come on, sit down for a second," Sera said, gesturing to the small plush sofa in the center of the room.

Kaelen hesitated, then slowly lowered his massive, heavily armored frame onto the couch. The cushions immediately compressed to their absolute limit under his divine weight, causing the archangel to sink hilariously low to the floor. His long legs were bent awkwardly, and his stoic, sharp-jawed expression remained completely unbothered despite looking utterly ridiculous.

Sera covered her mouth, her shoulders shaking as she let out a loud laugh. "Oh my god, Kaelen! You look like a giant sitting in a dollhouse!"

Kaelen narrowed his eyes at her, a subtle, dark flush creeping up his neck, though he kept his posture rigidly erect. "This mortal furniture lacks proper structural integrity," he gritted out defensively. "It is poorly forged."

"It's built for normal humans, not three-thousand-year-old warrior angels made of pure muscle and iron!" Sera teased, walking over to her small kitchen.

She opened the refrigerator door, only to be met with a bare lightbulb, a carton of expired milk, and half a bottle of water. She sighed softly. "Well, no surprise there. Everything's empty. Guess I'll have to order food instead."

Kaelen’s brow furrowed in confusion as he managed to extricate himself from the sunken sofa. "Order? You summon food through dark rituals?"

Sera laughed again, holding up her smartphone. "No, Commander. I tap a few buttons on this little box, a guy on a motorcycle brings a hot pizza to the door, and I pay him. Modern magic."

Kaelen stared at the glowing screen with deep suspicion, clearly weighing the strange logistics of mortal delivery services.

Before Sera could select a restaurant, a sharp, sudden knock echoed against the front door.

In an instant, the lighthearted mood evaporated. Kaelen’s hand was on the pommel of his great sword, his storm-grey eyes flashing with a dangerous, golden light as he stepped instantly between Sera and the entryway.

"Are you expecting someone?" Kaelen asked softly, his deep voice carrying a lethal, protective edge.

"No... nobody knows I'm back," Sera whispered, her heart starting to race.

She tiptoed past Kaelen, gesturing for him to stay back, and leaned forward to look through the small brass peephole.

Her breath caught. Standing on the porch outside, wearing a rain jacket and looking tired with dark circles under his eyes, was Mark.

"Mark?" Sera gasped under her breath.

Without thinking, she unlocked the deadbolt and pulled the door wide open.

"Sera?!" Mark gasped, his eyes going wide with pure shock and overwhelming relief. "Oh my god, Sera! You're okay!"

Before she could say another word, Mark stepped forward and wrapped his arms tightly around her, pulling her into a fierce, desperate hug. Relieved to see a familiar, friendly face from her normal life, Sera hugged him back just as tightly, burying her face in his shoulder.

Mark pulled back just an inch, his hands lingering on her arms, his eyes scanning her face with frantic worry. "Where have you been? I’ve been calling you every single day! The police said—"

"Mark, I'm okay," Sera breathed out, offering a weak, reassuring smile. "I'm so sorry I disappeared, I—"

"Ahem."

The low, thunderous clearing of a throat shattered the moment into a thousand icy shards.

Mark froze, his head snapping toward the dark interior of the apartment.

Standing right behind Sera, towering over both of them in the dim doorway, was Kaelen. His broad shoulders completely blocked out the hallway light, casting a long, terrifying shadow over Mark. The First Blade had not drawn his sword, but his hand rested heavily on its pommel, his storm-grey eyes burning with a lethal, possessive aura that turned the humid summer night air instantly frigid.

Mark instinctively took a step back, his face draining of color as he looked up at the terrifying, ridiculously imposing man standing in Sera's living room. "S-Sera... who the hell is this?"

Before Sera could formulate a lie, the air around them shifted.

The glowing streetlights outside the apartment building flickered once, twice, and completely died, plunging the hallway into pitch darkness. A sickening, metallic stench—like sulfur mixed with wet iron—filled the corridor.

Kaelen’s eyes ignited with a blinding, divine golden light. In a fraction of a second, he shoved Sera behind his back, his massive broadsword unsheathed with a deafening SCHWING that rattled the doorframe.

"Kaelen, what is it?!" Sera gasped, her heart dropping into her stomach.

"Underworld scouts," Kaelen growled, his voice vibrating with absolute fury as he locked his gaze on the end of the dark hallway. "They followed us."

Slowly, from the shadows at the end of the corridor, two glowing crimson eyes peeled open, followed by a low, guttural snarl that shook the floorboards beneath their feet.

Duke Malakor hadn't waited for the eleventh soul. He had come for her.
