They followed the trail of darkness, which led them to the entrance of the Underworld. The air was thick with the stench of brimstone and decay, and the ground trembled beneath their feet.
"This is it," Arin said, his voice barely above a whisper. "The Underworld."
Liana nodded, her eyes scanning the darkness. "I can feel the darkness growing stronger."
Jax took a deep breath. "Time to face whatever's waiting for us down there."
The three of them stepped into the Underworld, their hearts pounding with anticipation. They were greeted by a horde of demons and dark creatures, who attacked them with a ferocity that was almost overwhelming.
But Arin, Liana, and Jax fought bravely, their weapons shining with light. They battled their way through the Underworld, facing challenges and dangers at every turn.
