Hunting for the Culprit (3)

Ileus gathered Anastasia in his arms and motioned the others to stand facing the stone wall on the left side. As soon as they stood in a line in front of it, he nodded at Haldir. They pressed their hands on the wall and whispered a spell under their breath. The wall rippled like water, fell apart and his hand went through it. "Step inside," Haldir instructed others. 

Anastasia's mouth fell open as she watched the exquisite magic. Ileus pulled her inside with him. They all stepped inside the rock, which felt like a water tank, except that instead of water, there were fine pieces of stones floating around them in a thick gel-like state. Anastasia wanted to speak, but her voice couldn't be heard by anyone. She found herself seeing the room outside and wondered if they could also be seen. The wall was arranged back in its original shape, concealing the intruders. From the outside, it was just like before.
