The temple's ancient doors groaned open, revealing a pathway that descended into golden depths. Stone steps, worn smooth by centuries of pilgrim feet, spiraled downward into an ever-brightening glow. Elder Lucia stood at the entrance, her silver hair capturing fragments of light.
"The path tests all who descend," she warned, lighting a ceremonial lamp. "Each level brings its own challenges."
Xiaojin, perched on a nearby pillar, tilted its head at the lamp's flame. The phoenix's usual mischievous gleam slowly shifted to something more ancient as it sensed the power below.
"We should move quickly," Xiao Yan noted, observing another tremor shake the temple. "The core's instability is increasing."
Their descent began with Lucia and Benn in the lead, their lamps casting dancing shadows on walls covered in elaborate murals. Shanks followed, unusually quiet as he studied the ancient artwork depicting the island's founding.
The first challenge came several levels down, where the air itself seemed to thicken with golden mist. Each breath became harder, as if the very atmosphere resisted their presence.
"The Trial of Weight," Lucia explained, her steps becoming labored. "The light here carries substance."
Xiaolong, who had been playfully coiling around the stairs, straightened suddenly. The dragon's scales began to shimmer with a subtle electrical current, creating a field that pushed back against the heavy air. His usual playful demeanor gave way to something more regal, more befitting his divine nature.
"The air isn't heavy," Xiao Yan observed, watching his companion's reaction. "It's testing our resolve."
Uta, who had been humming softly, found her voice starting to resonate with the golden mist. The air seemed to lighten around them, responding to her melody.
Deeper they went, where the stairs opened into a vast chamber filled with floating crystals. Each crystal reflected light in different directions, creating a maze of brilliant beams.
"Step carefully," Lucia warned. "One wrong move and—"
A stray beam struck a crystal, multiplying instantly into a web of searing light. But before anyone could react, Xiaojin soared upward, its divine flames interacting with the light in ways that defied normal physics. The phoenix's movements were no longer the playful aerial displays of before, but precise and purposeful, each beat of its wings adjusting the crystal alignments.
"Show-off," Shanks grinned, though his eyes held newfound respect.
"No," Xiao Yan corrected quietly. "It's remembering."
They reached a chamber where the floor was broken into floating segments, gaps of undefined depth between them. Here, Xiao Gui, who had been quietly observing until now, stepped forward. The turtle's eyes held ancient wisdom as it tapped each platform with its beak, causing them to shift and align into a stable path.
"Your companions," Lucia observed, watching the display, "they grow more extraordinary with each level."
"They respond to the ancient power," Xiao Yan explained. "Like recognizing like."
The air grew thicker with power as they descended further. Xiaolong's electricity now crackled with purpose, creating a protective field around their group. Xiaojin's flames burned with increasing purity, less wild and more refined. Even Xiao Gui's movements carried a dignity that spoke of its true nature.
A final tremor shook the passage, stronger than before. Ahead, golden light poured through a massive doorway carved with warning symbols.
"The core chamber," Lucia announced, her voice hushed. "Though I should warn you, the guardians—"
She stopped as Xiaojin flew forward, its divine flames now burning with such pure light that it nearly matched the core's glow. Xiaolong's scales shimmered with controlled power, while Xiao Gui's shell began to resonate with the ancient energies.
"Your companions," Shanks said quietly to Xiao Yan, "they're not just what they seem, are they?"
"Few things are," Xiao Yan replied, watching his divine companions prepare to face what lay ahead. "Especially those who carry eternity in their nature."
The massive doors began to open, revealing the heart of Hikari Isle's power. As golden light washed over them, even Uta fell silent, sensing the shift from mortal concerns to something far more ancient.
The time for playfulness had passed. What lay ahead would require the true nature of divine beings, and Xiao Yan's companions seemed more than ready to answer that call.
