Regression of the Tower's Final Survivor-Chapter 37: The Infernal Gate

The fortress corridors twisted in ways that defied normal architecture, passages curving at angles that hurt the eyes to follow.

Passages that should have led upward curved back on themselves while rooms that appeared small from outside opened into chambers large enough to hold armies. Everywhere, the flames that lined the walls seemed to watch them, flickering in response to their movements like curious eyes.

"This place is wrong." Astrid muttered, her hand never straying far from her axe. "I’ve seen dungeon layouts before. This is something else."

"The fortress wasn’t built in this dimension." Dante led them through a corridor that he remembered from his original timeline, though the details seemed subtly different. "It was constructed in the Infernal Realm and transplanted here when the Tower absorbed that territory. The geometry still follows rules we don’t fully understand."

"That’s comforting." She rolled her eyes and tightened her grip on her weapon.

Ravenna walked slightly ahead of them all, drawn by something no one else could sense. Her Hellfire flickered constantly now, responding to the ambient energy of the fortress with eager pulses that cast dancing shadows on the obsidian walls.

"It’s getting stronger," she said, her voice distant. "The pull. Whatever’s waiting for me, we’re getting closer."

They encountered more enemies as they pressed deeper into the structure, and these weren’t just flame elementals but more sophisticated defenders: obsidian golems that moved with grinding deliberation, fire spirits that darted through the air with malicious speed, and something called a pyroclastic horror that filled an entire chamber with its magma-blooded bulk.

The horror was the first real challenge since entering the fortress, and it came at them with all the fury of a volcanic eruption made flesh.

"Ren! Shield wall!" He shouted, diving away from a spray of molten rock that would have melted through his armor.

The big man planted himself between the horror and Ravenna, his enchanted shield absorbing the brunt of the attack. Steam hissed from the metal surface, but it held. Barely.

Astrid circled to the creature’s flank, her berserker rage building as she searched for weak points in its rocky exterior. Her fists cracked against obsidian hide without visible effect, but each strike made the creature flinch, drawing its attention away from easier targets.

"Ravenna! Now!" He pointed at the creature’s exposed flank.

She was already waiting for the opening, Hellfire building between her palms until it burned even hotter than the horror’s own flames. The blast caught the creature mid-turn, punching through its magma core with surgical precision.

The pyroclastic horror collapsed in a shower of cooling stone and dying fire, its massive body crumbling into rubble.

[Enemy slain: Pyroclastic Horror]

[System points: +800]

[Party sync bonus: +200]

"Party sync bonus?" Ren shook molten droplets from his shield, examining the notification with interest. "I’ve never seen that before."

"It triggers when a party executes coordinated tactics effectively." He checked the others for injuries, finding only minor burns that Ravenna’s tentative healing abilities could address. "The system encourages teamwork. Most climbers never figure that out."

"Because most parties don’t function as actual teams." Ren’s smile was tired but genuine. "They’re just collections of individuals pursuing personal goals."

"Exactly." He nodded and gestured for them to continue. "Let’s move."

They continued deeper, following Ravenna’s instincts through corridors that seemed to reshape themselves to guide her specifically. The flames along the walls burned brighter as they approached, and the temperature, rather than increasing, settled into something almost comfortable.

---

The shrine revealed itself behind a wall of fire that parted at Ravenna’s approach, the flames peeling apart like curtains drawn back to welcome her.

It was ancient beyond estimation, carved from stone that predated the fortress itself with symbols covering every surface, spiraling patterns that seemed to writhe in the flickering light. The architecture was alien, built for beings shaped differently than humans, with proportions that made the space feel simultaneously cramped and vast.

At the center, on an altar that radiated power like heat from a furnace, a crystalline flame burned with colors that shouldn’t exist.

"This is it." Ravenna’s voice was hushed, reverent. "I’ve been dreaming about this place. Since Floor 1, maybe before. A fire that burns without consuming. A gift waiting for someone worthy."

"You didn’t mention those dreams." He frowned, concerned by her secrecy.

"I didn’t understand them until now." She turned to face him, and her eyes were already changing, flames flickering behind her pupils. "I think this is what I’m supposed to find. What I was always supposed to find."

He studied the altar with the wariness of someone who saw too many gifts become curses. The crystalline flame was beautiful, certainly, burning in colors that seemed to shift between purple and black and something else entirely. But beauty in the Tower often masked danger.

"We don’t know what it does." He stepped between her and the altar. "Taking power from unknown sources—"

"Is dangerous. I know." She stepped closer to the altar, her Hellfire reaching toward the crystalline flame like a child reaching for a parent. "But I also know this is meant for me. I can feel it in my blood, in the parts of me that come from my mother. This is a gift for her children."

"Your mother abandoned you. Left you to die." His voice was harder than he intended.

"She did, but she was still powerful, still connected to something older than the Tower." Ravenna looked at the flame, and longing filled her expression. "This is my inheritance. The only thing she ever left me."

The others spread out around the shrine’s perimeter, watching for threats while giving Ravenna space for her decision. Ren’s shield was raised, ready for anything, and Astrid paced with restless energy, clearly uncomfortable with standing still in hostile territory.

He moved to stand directly in front of Ravenna, blocking her path to the altar.

"If I asked you not to do this, would you listen?"

She met his eyes, and the conflict in her expression was painful to witness.

"I would try, for you I would try." She reached up to touch his face, her fingers warm against his cheek. "But it would hurt. Whatever’s in that flame, it’s calling to me in a way I can’t describe. Refusing it would feel like cutting off a limb."

"And accepting it might change you. Fundamentally." He caught her hand and held it against his face.

"I know." Her smile was sad and certain. "But I’m already changing. Have been since Floor 1, maybe since before. This just... accelerates the process."

He wanted to argue, wanted to drag her away from the altar and the power it promised, but the trust in her eyes stopped him, the absolute certainty that she knew what she was doing even if he didn’t understand.

"If anything goes wrong," he said finally, stepping aside, "I’m pulling you out."

"I know you will." She kissed him softly. "That’s why I’m not afraid."

She walked to the altar and placed her hands on the crystalline flame.

---

The transformation was immediate and overwhelming, power flooding into Ravenna visible as bands of light that wrapped around her body and sank beneath her skin.

She screamed, the sound equal parts agony and ecstasy, her back arching as something ancient and terrible reshaped her from the inside out.

He started forward, but heat erupted from the altar in waves that drove him back. Ren tried to reach her with his shield leading, but even the enchanted metal couldn’t withstand the concentrated inferno. Astrid’s roar of frustration was lost in the roar of the flames.

They could only watch as Ravenna burned, helpless despite their combined strength.

Then, suddenly, it was over.

The fire died, the heat subsided, and Ravenna stood at the altar’s center with her appearance subtly but unmistakably changed.

Her lavender skin shimmered now, as if flames danced just beneath the surface. Her horns, usually small and easily hidden, grew slightly, their tips glowing like embers. Her eyes, when she opened them, were no longer mismatched purple and blue.

They were both the color of burning coal, dark with glowing cracks that pulsed with inner fire.

[Infernal blessing acquired: Hellfire Affinity]

[Class evolution: Half-demon → Infernal Scion]

[New ability unlocked: Hellfire Incarnation]

[Administrator attention: Level 9]

"Ravenna?" He crossed the now-safe space between them, taking her face in his hands despite the heat that radiated from her skin. "Are you okay? Talk to me."

She looked at him, and slowly, a smile spread across her transformed features.

"I’ve never felt better." Her voice carried an undertone of crackling flame, deeper and more resonant than before. "I can feel everything now. The fire in the walls, the heat in the stone, the embers sleeping in the volcanic rock beneath us. It’s all connected, and I’m part of it."

"Your eyes are different. Your horns." He studied her face, searching for any sign of the person he knew.

"Good." She looked down at her hands, watching flames flicker across her fingertips without conscious effort. "I was tired of pretending to be something I’m not. This is who I really am."

Astrid approached cautiously, axe still in hand. "So what, you’re a fire demon now?"

"Infernal scion." Ravenna’s smile turned sharp, edged with power that didn’t exist an hour ago. "The system called it a class evolution. I’m going to use every bit of it to protect the people I love."

Ren lowered his shield, expression thoughtful. "How do you feel? Honestly."

"Whole, for the first time in my life." She looked at him, and the warmth in her gaze was the same warmth he always saw, the warmth that nothing to do with fire. "I understand what I’m supposed to be. Is that okay?"

He pulled her into his arms, ignoring the heat that seeped through his armor.

"As long as you’re still you, it’s more than okay."

They stood together in the ancient shrine, surrounded by power older than humanity, and for a moment the path ahead seemed clearer than it seemed since the regression began.

Ravenna was stronger now, and they all were, and they were going to need every bit of that strength for what was coming.
