The nursery was quiet, save for the soft hum of the desert wind filtering through the window. Aventurine sat beside the crib, his usually flamboyant demeanor replaced by an uncharacteristic stillness. In his arms rested a small bundle wrapped in soft, white fabric—his child. The baby stirred slightly, their tiny fists curling and uncurling, and Aventurine’s heart beat faster than it ever had at the gambling table.

He hadn’t prepared for this moment, not truly. For all his meticulous strategies and contingency plans, nothing could have readied him for the weight of fatherhood. He gazed down at the infant, his hair falling over his face as he adjusted the blanket.

“Come on, little one,” he whispered, his voice unsteady but warm. “Let me see those eyes.”

The baby stirred again, a soft whimper escaping their lips before they blinked slowly, their tiny eyelids fluttering open. Aventurine held his breath as two vibrant eyes were revealed—magenta and cyan, with the unmistakable black pupils of an Avgin.

His heart stopped.

For a moment, the world fell away. The distant sound of the wind disappeared, the weight of his past faded into silence, and all that remained was the tiny being in his arms. The sight of those eyes—so strikingly familiar yet entirely unique—triggered a torrent of emotions he wasn’t prepared to face.

Memories rushed in like an unbidden tide. His clan. His mother’s gentle voice. His sister’s laughter, long since silenced. The horrors he’d endured, the chains around his wrists, the pain of losing everything. And now, here was his child, carrying the unmistakable mark of their shared lineage. A lineage he had fought to preserve, even as he tried to bury its painful legacy.

Tears welled in Aventurine’s eyes, but he quickly blinked them away, his signature grin faltering for only a moment. “Well,” he finally managed, his voice soft and laced with an unfamiliar vulnerability, “aren’t you full of surprises, just like your old man.”

The baby cooed, their tiny fingers reaching out and gripping Aventurine’s thumb with surprising strength. He chuckled, a sound filled with both awe and disbelief. “You’ve got your Papa’s eyes, huh? I guess fate had a hand in this one.”

For the first time in years, Aventurine felt something he hadn’t allowed himself to feel: hope. This child was more than a reminder of his past—they were a chance at a future he never thought he could have. A future where his clan’s story didn’t have to end in tragedy. A future where this little one could live free, unshackled by the pain and cruelty that had shaped his own life.

He leaned down, pressing a gentle kiss to the baby’s forehead. “Don’t worry, little star,” he whispered, his voice trembling slightly. “I’ll make sure you never have to face what I did. I’ll give you a world worth seeing with those beautiful eyes.”

The baby blinked up at him, their gaze curious and unclouded by the weight of the world. Aventurine smiled, his resolve solidifying like the roll of a perfect hand. Whatever risks he had to take, whatever games he had to play, he would do it all for them.

In that moment, holding his child with their shared Avgin heritage shining back at him, Aventurine realized he’d already won the most important gamble of his life.
