**Chapter 49: The Shadow of the Past**
As they prepared to leave Lumina, a shadowy figure emerged from the ruins—a remnant of the ancient civilization, corrupted by centuries of darkness. This figure was **Kaelen**, a fallen guardian who had been consumed by regret and despair, now seeking revenge against the realm.
Kaelen revealed that the darkness was not only external but also rooted deep within the realm's history. His presence was a warning: darkness could take many forms, even from within.
Lina and her friends fought fiercely against him, but in the end, she chose compassion. She offered Kaelen understanding and forgiveness, reminding him that hope and change were always possible.
Moved by her kindness, Kaelen's spirit was freed from his torment, and he sacrificed himself to seal away a lingering shard of darkness, saving the realm from destruction.
