Right now, you're facing towards the wall. Turn left and move forward until you reach a opened door in front of you. Now, slightly turn left and enter into the room, where you will be facing towards a pillar. Now, turn left and move forward. You will come across a staircase. Walk all the way down through the stairs and continue to move forward until you reach a pillar in front of you. Now, turn left and move forward and stand at a point, where you can see a black dining table on the right and that is the end point.
