Lyra rushed to the city's central square, where the city mages were gathered. She quickly explained the situation to them, and they nodded gravely.
"We've noticed something strange too," one of the mages said. "People are acting... off. They're not themselves. We've tried to intervene, but nothing seems to work."
Lyra's eyes narrowed. "I think Nyx is using some kind of dark magic to control their minds."
The mages exchanged worried glances. "We need to find a way to counter it," one of them said.
As they worked together, Lyra realized that the city's ancient magic was tied to the city's founder, Elara. She remembered the story of Elara's powerful magic and her connection to the land.
"Guys, I think I have an idea," Lyra said. "What if we use Elara's magic to counter Nyx's? We can tap into the city's ancient power and create a spell that will break her hold on the city."
The mages nodded, eager to try anything. Together, they began to chant and weave their hands in intricate patterns, calling upon the ancient magic of the city.
As they finished their spell, a bright light burst forth from the center of the square. The air seemed to shimmer and ripple, and Lyra felt a surge of energy flow through her.
"Did it work?" she asked, looking around.
The mages cheered as people began to snap out of their trance-like state. They looked around confused, but free from Nyx's control.
Raven, who had been watching from a distance, grinned. "You did it," he said, relief washing over him.
But as they celebrated, Lyra noticed that Kaelara and Lirien were nowhere to be seen.
"Where are they?" she asked Raven.
He shook his head. "I don't know. I thought they were with you."
Lyra's heart sank. "We have to find them," she said.
