The entrance that was blocking the hidden passage moved.
It was a circular door that parted in the middle, this also the same thing that prevented Raven's spying. This door opened as soon as the guy earlier disappeared, maybe he's the one who opened it for them or he contacted others to do it for him.
Nevertheless, the two entered the tunnel behind the circular door. Victor lit up a torch and gave one to Raven as well, he then said:
"No matter how bright or dim this place is, no matter how good your eyesight, remember that we are only allowed to use regular torches as a light source and nothing else. Anyone who enters this tunnel must light up a torch or else they will be treated as infiltrators. Keep this in mind."
Victor's tone was full of solemnness which meant that he was serious, Raven kept this information inside his mind, and with how good his memory is, it is very unlikely that he will forget about his warning.
