Before entering the tavern, Rein cast a void magic spell called "Barrier of One Destination" to surround the whole place with a barrier which would stop the people inside from running away. Even though Rein had used a powerful spell, as a fifth rank mage he was able to hide his magical power very well and no one inside the tavern was able to sense it. Then Rein calmly entered the place.
Rein's appearance immediately made all the men inside to become cautious. This was a little known hidden tavern that some people were using to do shady things. So none of the people who appeared here were new faces. That was the reason why just seeing a new face like Rein was enough to make everyone alert.
Rein did not mind the attention that was put on him and instead used that to ask everyone if they knew where Letor was. Letor was the name of the man who Rein was looking for.
