Quick! Before the Hyena Come!

This cave was definitely the cave Natha was looking for. The opening was unnaturally formed and strange metal strips disappeared inside it. The work stank of hooman work. Her golden eyes peered deeper into the tunnel but there was only so much light. She felt her macaque, Ragna, rest a hand on her shoulders.

"Are you really sure you want to explore in there?" Natha nodded. She'd made up her mind to explore these strange hooman cave systems and that's what she was going to do. She stepped gingerly into the entrance, noting immediately the wooden beams that formed the entrance she'd just walked through. She assumed the hoomans had sculpted an existing cave into this strange shape but as she looked more she was wondering if this was the hooman version of a den. Had they dug their way in here?
