Fairy Forest—a place where time and eternity intertwine—lay serene under the gentle veil of morning mist. At its heart, the World Tree stood tall, its ancient roots anchoring the essence of the entire fairy realm.

Beneath its grand canopy stood a lone figure, motionless yet brimming with life—Caelum Alvarion, the immortal elder fairy. His wings, vast and majestic, seemed woven from moonlight and stardust, beautiful enough to make even flower fairies bow their heads in envy. His black hair flowed gracefully down his back, and his face held the timeless features of ancient divinity. His gaze was cold, like stars long extinguished but still shining faintly in the distant sky.

Unchanging and eternal, he remained indifferent to the small, fluttering fairies who danced beneath the branches. Until one day—

“Caelum!”

A crisp, bell-like voice shattered the stillness, audacious enough that the young fairies held their breath in disbelief.

By the fairy pond, a tiny fairy dangled her bare feet over the water’s edge, her delicate wings shimmering like morning dew. Her eyes sparkled like stardust as she called out his name—no honorifics, no hesitation.

Caelum turned slowly, his gaze slicing through the mist hanging over the water.

“…Say it properly.”

His voice was curt, colder than the dawn’s chill. Yet, she did not flinch. That little fairy—born from the branches of the World Tree, the only one entrusted by the gods themselves—simply tilted her head and smiled.

From that day on, the forest witnessed something strange. Caelum, whom even the elder fairies bowed to, began appearing near her far more often than necessary. No one saw him act, but whenever she was lost in the mushroom grove or too weak to fly across the spring river, a gentle breeze would always lift her across.

And every time she called his name—“Caelum”—without fear or reverence, he would frown, yet never stopped her. She never changed the way she called him, and he… never punished her.

For she was the only being who could touch the World Tree without being cast away, the small flicker of flame that slipped past the layers of ice that had sealed his heart for millennia.
