**Chapter 23: The Hidden Citadel**
As the realm settled into a tentative peace, Lina's team received word of a mysterious structure hidden deep within the Mistwood Forest—a place called the Hidden Citadel. Legends whispered that it held ancient relics, forgotten magic, and perhaps answers to questions Lina hadn't yet dared to ask.
Driven by curiosity and a sense of duty, Lina, Thalos, Pip, and Solara set out toward the dense, fog-laden woods. The trees were alive with whispers, and the air shimmered with magic—an ancient protective barrier guarding the citadel's secrets.
Upon reaching its gates, they found runes glowing with strange symbols. As Lina touched them, a voice echoed—a guardian spirit named Arion, who challenged their resolve.
"Only those worthy can enter," Arion declared. "To unlock the citadel's truths, you must prove your hearts are pure and your intentions true."
