Climbing up until her ears nearly ticked across the stone ceiling, Yvah saw that the tunnel seemed to end in more stone. But there was a flicker of light at the end without a shadow. One more hoist upward and she slipped into the tight enclosure. Once her tail flicked out of sight from her companions, the tunnel dipped into a sharp turn, and shortly led into the source of light. 

The rubble opened up to a tight, enclosed room with no visible exit. It was furnished haphazardly with gems, statuettes and other assorted treasures. Among them was a clattered pile of shaped steel that must've been armor, as broad as it was. There were two packs tossed into the same corner, each a little frazzled. The most prominent thing in the enclosure stood against the wall opposite Yvah. It seemed to be a guard, entirely oblivious of her presence, staring upward in what seemed like total boredom. Boredom, so close to obvious intrusion. He must have known. Yvah could still hear the party bickering behind her. But he couldn't have expected someone to find him, either. 

Upon seeing him, Yvah's ears flattened backward and her head stooped low, just low enough to see and remain unseen. Slowly, she gripped the staff strapped to her back, unable to pull it from its sheath in the confined space. Her claws dug into the lip of the tunnel and pulled her forward quickly until she perched at the mouth of the tunnel. By the time the guardsman looked in her direction, she had already dismounted, leaping to the center of the room and sprinting forward. Before he could react, the end of her staff already met the underside of his jaw, and her heel swinging widely to connect with the side of his head. He collapsed to the ground in an unconscious pile of scales and leather.

"Oh," she muttered to herself, awkwardly recovering from her combat stance and moving to a crouch. She poked the unconscious body with her staff to find no reaction. "I thought he'd last longer." 

Yvah shuffled over a bit to his things. Nothing useful. She rose, and the staff pressed into the ground. She lazily leaned on it and she scanned the room for a moment. There were some valuables here. Easily hidden ones. Maybe the others wouldn't miss them.

Yvah shook her head. "All clear, guys!" she called out at the tunnel.
