Regression of the Tower's Final Survivor-Chapter 79: The Cost of Power

The headaches started two days after the Graviton Beast.

Dante hid them at first, the way he hid everything that might make him look weak in front of people who needed to believe he was invincible. A slight squint against light that seemed too bright, a hand that pressed against his temple when he thought no one was watching, the occasional stumble that he passed off as uneven terrain.

But bodies kept score of the damage done to them, and his was running out of ways to compensate.

They’d found refuge in a Drift-Born settlement on one of the outer islands, a small community of native Tower residents who’d adapted to Floor 14’s chaotic physics through generations of careful breeding and stranger technologies. Their buildings moved with the gravity fluctuations instead of fighting them, structures that swayed and shifted and somehow remained standing through forces that would have destroyed conventional architecture.

The Drift-Born themselves were thin and elongated, their bodies shaped by centuries of variable gravity, and they watched the Lightbreakers with the cautious hospitality of people who knew that outsiders brought trouble but also trade.

"You should rest," Ravenna told him on the third morning, finding him on the observation platform where he’d been watching the void since before dawn. "Actually rest, not whatever you’re doing out here."

"I’m thinking."

"You’re avoiding sleep." She moved to stand beside him, close enough that their shoulders almost touched. "The nightmares are getting worse."

He didn’t ask how she knew. Her demon senses probably told her everything about his emotional state, including the terror that waited for him every time he closed his eyes.

"The Core is fighting me," he admitted, surprising himself with the honesty. "Every time I use it, every time I push too hard, it pushes back. And the pushing back is... not pleasant."

"Define not pleasant."

He turned to look at her, and she inhaled sharply at whatever she saw in his face. His eyes were bloodshot, dark circles carving hollows beneath them, and there was a tremor in his hands that hadn’t been there a week ago.

"The power I used against the Graviton Beast should have killed me," he said quietly. "The Core isn’t meant to be used that way, not by someone who hasn’t spent years learning to harmonize with it. I’m essentially running a reactor without shielding, and the radiation is starting to cause problems."

"Problems like?"

"Headaches. Nosebleeds. Muscle tremors. Loss of coordination." He looked away, back toward the void. "Memory fragmentation, eventually. And after that..."

"After that?"

"The Core wins." He said it flatly, without emotion. "It stops being a tool I use and starts being a thing that uses me. I’ve seen it happen to other climbers who found power they couldn’t control, they become something else. Something that wears their face but isn’t them anymore."

Ravenna was quiet for a long moment, processing what he’d just told her with the careful intensity of someone deciding how to respond to a confession that changed everything.

"Why?" she asked finally. "Why use it if you knew this would happen?"

"Because you would have died." He met her eyes, and there was nothing cold or calculated in his expression. Just exhaustion and something that might have been fear. "The beast’s attack would have killed everyone in that chamber. The only way to stop it was to match its power output, and that meant using the Core in ways I wasn’t ready for."

"So you sacrificed yourself."

"I bought time." He turned away again. "There might be solutions. Ways to stabilize the connection before it destabilizes me. But I need time to find them, and I don’t know how much time I have."

"Then let me help." Ravenna reached out and took his hand, her fingers warm against his cold ones. "Let the team help. You don’t have to carry this alone."

"I don’t know how to let people help." The admission came out rough, pulled from somewhere he usually kept locked away. "In my experience, relying on others is how you end up dead."

"Your experience was a different timeline." She squeezed his hand once, gently. "This time, you have people who chose to be here. Who chose you. Maybe it’s time to start believing that means something."

He didn’t respond, but he didn’t pull his hand away either.

Sera found him that afternoon, approaching with the careful determination of someone who’d been rehearsing what they wanted to say.

"I need to check your injuries," she said, her healer’s staff already glowing with diagnostic magic. "The fight with the Graviton Beast left everyone with minor damage, and I want to make sure nothing is festering."

"I’m fine."

"You’re lying, and we both know healers can tell." She gestured toward a private alcove in the Drift-Born structure where they were staying. "Five minutes. That’s all I’m asking."

He could have refused. Could have pulled rank, dismissed her, made it clear that the leader didn’t submit to examinations by subordinates. But something in her expression, a mix of concern and the particular stubbornness of someone who’d decided they were going to help whether you liked it or not, made him follow her instead.

The diagnostic magic was gentle, waves of green energy that washed over his body and returned to her with information about his physical state. Sera’s expression remained neutral at first, professional calm maintained through training and practice.

Then she reached his Core, and her face went pale.

"What?" Dante caught her wrist before she could pull back. "What did you find?"

"I don’t... I’ve never seen anything like this." Her voice was barely above a whisper. "The energy running through you, it’s not flowing properly. It’s fighting itself, building up pressure at points that shouldn’t have pressure at all. Your entire mana system is destabilizing."

"I know."

"You know?" Her eyes went wide. "You know and you’re not doing anything about it? Dante, this is going to kill you! Maybe not today or tomorrow, but weeks? Months at most? Your Core is tearing itself apart, and it’s going to take you with it."

"How long?"

She stared at him, her mouth opening and closing as she processed the question.

"I can’t give you exact numbers," she said finally. "But based on the rate of degradation I’m seeing, and assuming you don’t use the Core again in any significant way, maybe six weeks. If you keep pushing it like you have been? Days. Maybe hours during combat."

Dante absorbed that information with the same calm he brought to tactical assessments, filing it away as another data point in a problem he needed to solve.

"Can you fix it?"

"I don’t know." Sera’s voice cracked slightly. "This isn’t a normal injury, it’s not something I can just heal. The damage is happening at a level I barely understand, the interaction between your spirit and this power you’ve bonded with. I’d need to study it, research, talk to people who know more about ancient artifacts than I do."

"Then do that."

"What?"

"Research. Study. Talk to whoever you need to talk to." He met her eyes steadily. "But don’t tell the others. Not yet."

"Dante—"

"If they know, they’ll try to protect me. They’ll hold back in fights, make decisions based on keeping me safe instead of completing objectives. And that will get them killed faster than my Core instability will get me killed."

"That’s not your decision to make," she said quietly.

"It is exactly my decision to make." His voice carried an edge that made her flinch. "I am their leader. I am responsible for their survival. And I will not let my personal problems become the thing that destroys them."

The silence stretched between them, heavy with things neither of them wanted to say.

"I’ll research," Sera said finally. "There are texts in the Anchor’s library about ancient power sources, and the Keepers might know something about stabilizing chaotic energy. But I’m not promising to keep this secret forever. If I find something that requires the team’s involvement, I’m telling them."

"Fair enough."

"And you’re going to let me monitor you." She crossed her arms, her healer’s authority asserting itself despite the difference in their positions. "Regular check-ups, every two days minimum. I need to track the degradation rate, establish a baseline so I can tell if something changes."

"Agreed."

She studied him for a moment longer, something shifting in her expression that he couldn’t quite read.

"You really would die for them," she said softly. "Without hesitation. Without regret."

"They’re mine." The words came out with a certainty that surprised even him. "And I don’t lose what’s mine."

Sera nodded once, slowly, then gathered her staff and left him alone in the alcove.

That night, Dante dreamed of the Core.

Not the Ancient Core as it was now, a source of power he barely understood and couldn’t fully control, but as it had been: a nexus of creation, older than the Tower, older than humanity, a fragment of something that existed before the concept of existence had meaning.

In the dream, it spoke to him.

’You are fighting the wrong battle.’

Dante stood in a void that wasn’t the void between Floor 14’s islands but something deeper, more fundamental. The Core floated before him, green-gold light pulsing with the rhythm of a heartbeat that had been running for eons.

’I need to control you,’ he said, or thought, or simply was. ’Otherwise you’ll consume me.’

’Control is the illusion of the weak. You cannot control a sun by grasping it. You can only learn to exist within its light without burning.’

’Then teach me. Show me how to survive this.’

The Core pulsed brighter, and suddenly he was somewhere else: a memory that wasn’t his, a time before the Tower, when the power he carried had been wielded by hands that didn’t shake with the effort.

’The answer is not in domination,’ the Core whispered. ’The answer is in harmony. Find the balance, and you will find peace.’

’How?’

But the dream was already fading, the Core’s light receding into darkness that swallowed everything except one final word:

’Trust.’

Dante woke gasping, covered in sweat, the taste of something ancient and powerful still lingering on his tongue.

The Core hummed beneath his ribs, and for just a moment, the pain was less. Not gone, and certainly not healed, but it was less. Maybe that was a start.
