The moment they stepped inside.
The massive door behind them slammed shut.
The first thing that greeted them was crumbling ruins scattered everywhere, surrounded by dense, unruly vegetation.
An air steeped in history washed over them.
As an "ancient mythology scholar," Cynthia immediately became interested the moment she saw the ruins.
She walked to the nearest broken wall, where faint patterns were still etched into its surface, though time had reduced them to little more than shadows.
After gently rubbing it twice, she said softly,
