The first echo was located in a realm known as the **Mirror of Eternity**, a place where reality itself seemed to reflect and distort. The air was thick with the scent of ozone, and the ground beneath their feet seemed to hum with power.
As the group approached the echo, they were confronted by a massive creature of light and shadow. Its voice echoed through the air, filled with malice. "**You cannot stop me, Kael Ardent. The multiverse will fall, and your efforts will be in vain.**"
Kael's grip tightened on the Entropy Compass. "We'll see about that."
The battle was fierce. The creature's attacks were precise and deadly, its shadowy form slicing through the air with ease. Kael channeled the Well's energy, his attacks precise and deadly. Lyra and Aegis fought side by side, their combined efforts turning the tide.
But the creature was relentless. Its power seemed to grow with every passing moment, its shadowy form expanding to fill the realm. Kael could feel the strain on his body and mind, but he pushed through, his determination unwavering.
As the battle raged on, Kael realized that the only way to defeat the creature was to merge the Well's energy with the Entropy Compass. It was a risky move, but he knew it was their only chance.
With a final burst of energy, Kael channeled the Well's power into the Compass, creating a weapon of pure light. The creature let out a roar of frustration as the weapon struck its core, its form dissolving into shadow.
As the light faded, the realm began to stabilize, its chaotic energy subsiding. But as the group prepared to leave, Kael collapsed to his knees, his body trembling under the strain.
Lyra rushed to his side, her voice filled with concern. "Kael, are you alright?"
Kael took a deep breath, his voice steady but tinged with exhaustion. "I'm fine. Just... tired. The Well's energy—it's not just about power. It's about balance. Every use takes a piece of me."
