Something drastic and mysterious started to happen in the passage where Zain and Sebastian were.
First, the bricks on the two opposite walls began to move individually. Right now they seemed to have realized what was happening.
"Holy smokes..." muttered Sebastian, with his eyes wide in astonishment.
Sebastian saw it first. He quietly tapped on Zain's shoulder, pointing at the wall.
"Oh my god..." muttered Zain, "What is happening?"
As the bricks twisted and turned, the walls were getting more wide apart than they were. It was creating a low rumbling sound, and the place was vibrating.
"Something's not right," said Sebastian, in a deep voice.
"I know something is not right," replied Zain, holding up her blade.
"Stay focused, be ready for anything," she said.
