The Aethelian Sky-Islands were a world divorced from the laws of the one below. Ren stood on the edge of their chosen sanctuary, a floating landmass the ancient Raijin charts had named 'Aerion's Rest'. Below him, a sea of brilliant white clouds stretched to an infinite horizon, a floor for the gods. The air was thin, crisp, and carried a strange, sweet scent, like ozone and wild blossoms. It hummed with an Aether so pure and so potent it felt like breathing liquid energy.
Anya had established a small, efficient base camp near the hidden entrance to the Nautilus, her salvaged equipment now forming a network of sensors and fabricators. She was in her element, a scientist presented with an entirely new, impossible ecosystem to catalog.
"The atmospheric pressure here is 70% that of sea level," she commented, her eyes glued to a data slate. "And the gravitational field is… inconsistent. It fluctuates based on the Aetheric density of the cloud-sea below. It's a miracle anything can grow here at all."
The flora was unlike anything Ren had seen. The trees were tall and impossibly slender, their roots not buried in soil but woven into the crystalline rock of the island itself. Strange, luminous blue flowers, which Anya had dubbed 'Sky-Lilies', grew in abundance, their petals collecting ambient Aether like dew.
This was the forge. Ren's path to the peak of the Disciple realm would begin here.
He found a secluded plateau, a flat expanse of the same crystal-laced rock, and sat. He closed his eyes and began to cultivate, reaching out to the vast, pure reservoir of Aether that surrounded him. He expected a flood. He received a frustrating, almost mocking, trickle.
The Aether was there, potent and willing, but it was… light. Ethereal. Trying to draw it into his core was like trying to catch mist in a net. It flowed around him, through him, but refused to be anchored.
"You are trying to draw water from a well meant for the wind," Zephyrion's voice echoed in his mind, tinged with a rare amusement. "The Aether of this place is attuned to the sky. It rejects the grounded. Your cultivation methods are those of the earth, of brute force and deep roots. They are useless here."
"Then how do I cultivate?" Ren asked, his frustration mounting.
"You wish to drink the wine of the sky?" the spirit replied. "Then you must first learn to dance in its halls. The power here will not answer to a master of the earth. It will only answer to a master of the storm. You must fly."
The lesson was clear. His path to Rank 26 was not through meditation, but through mastery.
He stood, and with a surge of will, unleashed the Phantom Wings of the Storm. The massive, draconic wings of azure lightning erupted from his back, their brilliant light a stark contrast to the clear, sunlit sky. He pushed off the ground, a powerful downbeat propelling him into the weightless air.
And he immediately began to fall.
He had expected the exhilarating freedom he'd felt in the Cinderwood, but the air here was different. It was alive, filled with treacherous, invisible currents and pockets of shifting gravity. His powerful wings beat against the air, but found little purchase. He was a swimmer trying to push against smoke. He tumbled, disoriented, the sea of clouds below rushing up to meet him.
Panic flared, but his training took over. He used a sharp, jarring burst of Raijin's Flash to halt his descent, reappearing a hundred feet higher, his body slick with a cold sweat.
"Unstable flight pattern detected," Anya's voice came through his comm-bead, crisp and analytical. "You are fighting the local thermals. The Aetheric updrafts from the cloud-sea are creating vertical wind shear. You cannot overcome it with raw power. You must learn to ride it."
Her voice became his guide. She was his ground control, her sensors painting a picture of the invisible world he was fighting. For hours, the sky became his training ground. It was a brutal, humiliating, and exhausting process. He would soar, only to be caught by a sudden crosswind that would send him into an uncontrollable spin. He would try to gain altitude, only to hit a pocket of low-gravity that would send him careening higher than he intended, leaving him exposed.
Time and again, he was forced to use Raijin's Flash to save himself, a jarring, inefficient use of his precious Aether. But with each failure, he learned. He stopped trying to fight the sky and started to listen to it. He extended his own senses, feeling the subtle shifts in pressure, the flow of the Aetheric currents. He began to use small, precise kinetic pulses to create pockets of stability around himself, small anchors in the chaotic air.
He learned to angle his lightning wings, not just to beat against the air, but to catch the updrafts, to glide on the invisible rivers of the sky. He was no longer a brawler throwing his strength at a problem. He was becoming a part of the ecosystem.
After three days of this grueling, relentless practice, something finally clicked.
He was caught in a particularly violent downdraft, the force of it pushing him relentlessly towards the cloud-sea. Instead of fighting it, instead of flashing away, he folded his wings and dove with it. He fell for a thousand feet, a silent blue comet, feeling the storm's energy, matching its rhythm. Then, at the last possible moment, he snapped his wings open, catching the energy of the current and converting it into a breathtaking, vertical ascent.
He shot back into the sky, not as a clumsy fledgling, but as a true master of the air. He hovered effortlessly, the wind no longer his enemy, but his willing servant. He hung in the sky, the islands spread out below him, a true lord of this new domain.
In that moment of perfect, effortless harmony with the sky, he felt the Aether of the island finally open itself to him. It was a floodgate of pure, weightless energy, and it surged into his core, not as a trickle, but as a willing, joyous torrent.
He closed his eyes, hovering in the center of a swirling vortex of pure, sun-drenched power. The barrier to the next rank, which had felt so impossibly distant just days before, began to crack under the strain.
With a final, silent roar of power, it shattered.
His Aether settled, denser, purer, and stronger than before. He had done it. He had earned his first step on the long climb. He had reached Rank 26.
