Yes, buddy, I know about that bar. One of my friends got a job there, since there I have not seen him .... He sent me the coordinates and left a message on the mobile. But I never wanted to go there and I still can't understand what he meant.
Here is the message:
Please, buddy, please! By the time you read this message, I'll be dead. But I know, I know how to kill them. I hid the name of the bar on the wall. Match the map and the word that you found in the sea to find that place.
Once you are there, look for the code on the building extension at the back: the name of the bar is on the wall. Then go to the place but don't forget to take an aspen stake or a cross, or holy water with you. It is very important. Otherwise, you will not manage.
