The battle raged on, with Luna's moonlight-infused sword clashing against the Shadow King's dark minions. Kaidën and Aethon fought in tandem, their magic and martial skills honed to perfection. Eli's own powers surged, her heart pounding with determination.
As the fight intensified, Eli began to notice subtle inconsistencies in Aethon's actions. The ancient warrior seemed to be holding back, his strikes less precise than usual.
"Aethon, what's wrong?" Eli asked, her voice barely audible over the din of battle.
Aethon's gaze flickered.
"Nothing, Elianor. Focus on the fight."
But Eli's instincts screamed warning. She observed Aethon's movements, realizing he was deliberately leaving openings for the Shadow King's attacks.
"Aethon, you're—"
Eli's words died on her lips as Aethon's eyes locked onto hers. For an instant, Eli saw a glimmer of darkness within.
"Aethon, no!" Eli shouted.
Kaidën and Luna turned, sensing Eli's alarm.
Aethon's expression twisted.
"I'm sorry, Elianor. I have no choice."
With a swift motion, Aethon struck down Luna, sending her crashing to the ground.
"Traitor!" Kaidën roared.
The Shadow King's laughter boomed.
"Welcome, Aethon. Your loyalty is rewarded."
Aethon's face contorted.
"I did it to protect our realm...to ensure Aethereia's survival."
Eli's heart shattered.
"Aethon, how could you?"
Aethon's voice cracked.
"I was promised power...and protection for our people."
Kaidën charged forward.
"Aethon, you've doomed us all!"
The Shadow King intervened.
"Enough. Aethon, bring me Eli's heart."
Aethon's gaze dropped.
"I'll do it. For Aethereia's sake."
Eli's world crumbled.
