Chapter 405: Eden’s Missing Requirement

Stillwater Basin looked nothing like the dangerous frontier Arthur had imagined. Clear pools spread between pale stone terraces, reflecting the morning sky in different shades of blue. Thin ribbons of light drifted above the water, occasionally slowing or bending while everything around them continued moving normally.

Eden hovered beside Arthur, following one of the ribbons with wide eyes. "It’s like the whole place is moving to a different rhythm. Look! That one keeps falling behind the others."

"You noticed already?" Athena asked, inspecting the portable instrument Celia had brought from the Academy. "The Mana readings confirm it. Those currents are crossing the same space at slightly different intervals."

Sun looked between the identical-looking pools. "I see water, rocks, and more water. How do you know which one’s late?"

Athy tilted her head. "By watching instead of talking."

Kong nodded solemnly. "Hard for Sun."

"I walked into that one," Sun admitted as Mithra laughed.

A researcher in a grey field coat met them outside the observation station. Her name was Mara, and she had already received the caravan merchant’s authorization letter. After checking Celia’s credentials, she led them onto a sheltered platform above the Basin.

"Your access covers the calibration instruments, not unrestricted entry into the currents," Mara explained. "If a reading exceeds the safe threshold, the trial stops automatically. Is your Fairy still recovering from a high-cost temporal ability?"

"Yes," Arthur answered. "She’s improving, but I won’t let her push herself."

Eden folded her arms. "I won’t push myself either. I learned that already."

Vedas smiled and inspected the padded resting bench beside the platform. "Good. Then we’ll keep this ready in case you need a break."

Star bounced onto the bench, testing its softness, then curled into a little star-filled cushion. Eden giggled. "Star thinks it’s comfortable!"

...

Mara activated three crystal markers suspended inside a transparent chamber. Each traveled along a circular track, while three naturally fluctuating Mana streams passed through their intersections. A blue marker moved through the center; two amber markers crossed its route at different intervals.

"The goal is to guide the blue marker through both intersections without stopping the system," Mara explained. "A small temporal adjustment is permitted. If you leave any residual distortion, the calibration fails. The conditions aren’t dangerous within the chamber, but the timing won’t remain constant."

Arthur opened Eden’s evolution information, remembering the condition they’d discovered in the Academy archive.

[Additional Evolution Data Unlocked]

[Chrono Fairy]

[Requirement: Demonstrate stable temporal control within a naturally fluctuating temporal Mana field.]

[Progress: Not Yet Completed.]

"This is what we came for," Arthur said. "Not a bigger spell or more Mana. You just need to keep the adjustment stable while the currents change."

Eden looked at the moving crystals, then at him. "Like Steven’s spheres, only the tracks don’t keep the same rhythm?"

"Exactly," Athena replied. "The obstacle isn’t speed alone. It’s uncertainty."

Mithra leaned against the railing beside Arthur. "Remember how you told me not to solve every problem for your Beasts during training? I think this one belongs to Eden."

Arthur smiled. "I know. I’ll be cheering, not directing."

Mara checked Eden’s condition with a small Mana gauge and confirmed that a brief, low-intensity attempt was acceptable. "One controlled adjustment, then we’ll examine the reading. If you feel discomfort, stop immediately."

Eden nodded and floated forward, holding her hands close to her chest. "Okay. I can do this."

The first cycle began. Eden watched the blue marker approach the first crossing, calculating its speed against the amber light. She waited until the same moment she’d used in Steven’s exercise and released a tiny temporal pulse.

The blue marker slowed neatly, allowing the first amber marker to pass. Eden smiled, but a bright current suddenly accelerated through the second crossing. The blue marker arrived too late and drifted outside the permitted track.

A low chime sounded.

[Calibration Attempt Unsuccessful.]

[Residual Temporal Distortion: Within Safe Limits.]

Eden’s shoulders dropped. "I thought I understood it. I used the same timing that worked before."

Sun winced. "That looked perfect until the second stream sped up."

"Which is the point," Athena said thoughtfully. "The environment isn’t repeating a fixed pattern."

Arthur moved closer but didn’t give Eden a new sequence to follow. "What do you think went wrong?"

Eden watched the recording Mara replayed. Her first adjustment had worked, but it also changed when the blue marker would reach the second intersection.

"I fixed the first part without looking at what would happen afterward," she said slowly. "And I assumed the second current would stay the same."

"That’s a good observation," Arthur replied. "What would you change?"

Vedas rested his spear against the railing. "You don’t have to control every crossing. Some problems may solve themselves if you know when to leave them alone."

Eden stared at the moving markers. "Then... I should wait longer before deciding."

Mara checked the gauge again. "You’re well within the safe limit. If you’d like one more attempt after a rest, we can allow it."

"I do," Eden replied. "But first I want to watch a few cycles."

Arthur grinned. "That sounds like a plan."

...

For several minutes, Eden sat beside Star and studied the chamber. Sometimes the first amber marker crossed early; sometimes it lagged. She began noticing that the three currents occasionally aligned just long enough for the blue marker to pass with almost no help at all.

Melo peered over Mithra’s shoulder. "She’s been quiet for ages. Is that a new record?"

"Don’t distract her," Mithra whispered, although she was smiling. "She’s figuring something out."

Eden rose when Mara restarted the calibration. This time, she didn’t immediately gather Mana. She watched the first crossing approach and allowed the blue marker to pass untouched through a natural gap.

Arthur’s eyes widened. "She didn’t need to slow it at all."

Then the second current shifted earlier than its previous cycles. The blue marker was headed straight toward the approaching amber light.

Sun gripped the railing. "She’s going to miss it again!"

Arthur nearly warned her, but Vedas gently raised a hand. "Wait. She’s watching it."

Eden remained focused. Instead of reacting to the immediate danger, she followed the fluctuating light until the next brief alignment began forming. She made one tiny adjustment, accelerating the blue marker just enough to clear the crossing before the amber marker arrived.

For a moment, the lights looked as if they might touch. Then the blue marker slipped through and returned to its ordinary speed, with no ripple following it.

The last instrument flashed gold.

[Temporal Calibration Successful.]

[Residual Temporal Distortion: None Detected.]

[Control Stability: Confirmed.]

Eden stared at the chamber. "Did... did I do it?"

Arthur raised both arms. "You did! You waited for the right opening and made exactly the adjustment you needed!"

Mithra applauded, while Sun shouted loud enough for Mara to flinch. Kong clapped beside him, and Athy gave a pleased nod.

"No wasted movement," Athena said, impressed. "And no residual distortion. That’s much more precise than her first attempt."

Mara studied the record again, then smiled at Eden. "I’ve seen far more experienced temporal specialists attempt to correct every fluctuation. You recognized that the currents were helping you. Excellent work."

Eden looked down at her hands, surprised by how steady they felt. "I barely used any Mana. I didn’t need Future Manifestation at all."

"You didn’t," Arthur said, holding out his arms. "You trusted what you saw. I’m really proud of you."

She flew into his embrace, laughing as she hugged him. "I did it, Arthur! I really did it!"

Vedas smiled warmly. "You made the decision yourself. That’s something no one else could have earned for you."

Star bounced up between them, wrapping around Eden’s arm. She hugged the little slime too, and its tiny crown tilted sideways.

...

A familiar blue window appeared before Arthur.

[Synchronization Increased]

[37% → 39%]

He blinked, then smiled even wider. Their shared understanding had deepened as Eden learned to make her own decisions.

Another notification followed.

[Additional Evolution Data Updated]

[Chrono Fairy]

[Requirement: Demonstrate stable temporal control within a naturally fluctuating temporal Mana field.]

[Progress: Complete.]

Arthur read the message again to make sure. The obstacle that had seemed so distant on Sunday was finally behind them.

"Eden, your evolution requirement is complete," he told her. "We actually did it."

Eden pulled away just enough to look at him. "Then can I evolve now?"

Arthur glanced toward Mara and Celia. "We’re close. But before we begin, we’re making sure you’re completely recovered. I promised I wouldn’t rush you into something dangerous."

Eden puffed her cheeks for a moment. "I was going to say we could start right away." She paused, remembering the blue marker passing safely because she had waited. Then she smiled. "But waiting was how I succeeded, wasn’t it?"

"Exactly," Arthur said, laughing. "You’re getting better at this than I am."

Celia offered to help arrange a final recovery examination at the station, while Mara saved the successful calibration record for the Academy. Sun suggested celebrating immediately, and Kong agreed before anyone mentioned food.

Mithra slipped beside Arthur as the others began discussing lunch. "You kept your promise to her. That means a lot."

Arthur watched Eden happily telling Star about the experiment. "She worked hard for this. I just helped her find the right place."

"That’s what made it a good promise," Mithra replied, lightly taking his hand.

...

That evening, Eden sat beside Arthur overlooking the quiet pools. The last sunlight made the drifting currents shine silver, and her completed evolution condition glowed before his eyes.

"Arthur," Eden asked, leaning against his arm, "what do you think I’ll look like after I evolve?"

He smiled, imagining all the possibilities still waiting beyond her current species. "I don’t know. But I bet it’ll be amazing."

Eden watched the lights move across the water, her wings fluttering gently. For the first time in days, she wasn’t comparing herself with Vedas or Star. She was thinking about what she might become.

"I can’t wait," she whispered.
