Prologue: Secrets in Moonlight

The moon bathed the sprawling palace of Aethel in an ethereal glow, casting long shadows from the ornate spires that pierced the velvet sky. Xana, barely a woman at sixteen summers, pressed her back against the cool stone of the palace wall, her heart hammering a frantic rhythm against her ribs. Her crimson hair, usually pulled back in a severe bun, had come loose in her haste, cascading down her back like a fiery waterfall. Sweat beaded on her brow, a traitorous sheen blemishing the carefully applied layer of servant's mud that usually masked her features.

Tonight wasn't laundry night, nor was she fetching misplaced scrolls from the forbidden library. Tonight, Xana was a trespasser, a shadow flitting through the forbidden halls of the Imperial Wing. Her nimble fingers traced the cold silver of a key – a trophy from a daring raid into the Head Chamberlain's chambers – the key that promised to unlock the secrets of her past and a potential lifeline for the future.

Growing up in the underbelly of Aeria, the capital city, Xana had always felt like a puzzle with missing pieces. Whispers about her origins followed her like a phantom limb. Her parents, humble merchants it was said, had perished in a fire when she was an infant. She was raised by a gruff but kind old woman named Elara, who instilled in her an unwavering sense of justice and a fierce independence. Elara, however, had always remained tight-lipped about Xana's past, deflecting questions with a cryptic, "Some truths are best left undisturbed, child."

The turning point came a fortnight ago. Xana had been on a routine delivery to the palace kitchens when she overheard a heated exchange between two guards. They spoke of a "marked one" smuggled into the palace as a babe, a child with an "abomination" hidden beneath their swaddling clothes. It was like a shard of ice piercing through her foggy memories. A childhood nightmare, a recurring vision of a midwife's panicked face contorted in horror, a whispered plea about "hiding the mark" – it all flooded back with terrifying clarity.

The whispers that had always swirled around her – about her unusual strength, her tolerance for pain, the way her body seemed to defy categorization – suddenly clicked into place. Xana wasn't just different; she was an abomination in the eyes of the Empire. In Aeria, a rigid social order dictated every aspect of life. Men were the warriors, the leaders, their bodies vessels of strength and power. Women were the nurturers, the keepers of the hearth, their forms symbols of fertility and beauty. Anyone who fell outside this rigid binary was ostracized, hunted even, by the merciless Order of Purity, religious zealots who saw them as a blight upon the land.

Terror had been Xana's first reaction, a cold, suffocating wave that threatened to drown her. But then, a fire ignited in her belly, a fierce determination to understand her history and fight for a future where difference wasn't a curse. Elara, on her deathbed a few days later, finally revealed a hidden compartment in their meager belongings – a small chest containing the very key Xana now held. "They branded you, child," Elara had rasped, her voice laced with a lifetime of fear and defiance. "But your strength is your own. Find the truth, Xana. And fight for a world where the moon shines on all."

The key felt heavy in Xana's palm, a tangible link to her ostracized identity. She glanced around nervously, the silence broken only by the distant murmur of conversation and the rhythmic click of patrolling guards. Steeling her nerves, she crept down the passage, the ornate tapestries swaying ghostly in the draft. Her destination: the Imperial Archives, a labyrinthine repository of the Empire's history and secrets.

Reaching the imposing oak door leading to the archives, Xana inserted the key with a deep breath. It turned with a soft click, sending a thrill of anticipation through her. But just as she reached for the handle, a voice sliced through the silence, harsh and laced with suspicion.

"And who might you be, skulking about in the dead of night?"
