The heroes set off, gathering the ancient artifacts and preparing for the final battle. They traveled across the land, facing challenges and dangers at every turn.

Thane nodded, his face set. "We have to move faster," he said.
The heroes quickened their pace, their senses on high alert. They knew that they were running out of time.
