Kael's resolve crumbled beneath Niamh's seduction. Her darkness enveloped him, tantalizing and treacherous.
"Eli's trust," Kael whispered, his final defense.
Niamh's laughter echoed. "Trust is a fragile thing...easily broken."
Kael's control slipped. Niamh's touch ignited a forbidden spark, and he surrendered to the shadows.
In the mortal realm, Eli sensed Kael's fall. Her heart shattered.
"Aethon, Kael's lost," Eli cried.
Aethon's face hardened. "We must bring him back."
Together, they ventured into the dark realm, navigating treacherous landscapes.
"Niamh's powers grow," Arianna warned. "Be cautious."
Eli's determination burned. "We won't abandon Kael."
As they reached Niamh's stronghold, Kael's voice echoed.
"Leave me be," Kael growled.
Eli's heart ached. "Kael, come back to us."
Kael's eyes gleamed with darkness. "I've found my true home."
Niamh's smile twisted. "Welcome, Eli. Witness Kael's rebirth."
Eli's resolve strengthened. "We'll save Kael, no matter the cost."
Aethon's sword flashed. "We'll fight for our brother."
The battle for Kael's soul began.
