Sera raced to the ritual chamber, her heart pounding in her chest. She found the chamber exactly as she had seen it in her vision: the Shadow Walker standing in the center, chanting in a guttural language.He was surrounded by a circle of black candles, their flames casting eerie shadows on the walls. He was performing a ritual to break the seals that protected the threshold, to unleash the darkness upon the world.Sera confronted him, her voice trembling with anger. "Stop!" she cried. "You will not succeed."The Shadow Walker turned to face her, his eyes burning with malevolent energy. "You cannot stop me, Sera Blackwood," he said, his voice a chilling whisper. "The threshold will be ours."He lunged at her, his hand outstretched, his fingers tipped with razor-sharp claws. Sera dodged his attack, summoning her own energy, preparing to fight.
