Simply -having- to explore every inch of this place, you then decide to walk up the stairs. With each step, the wooden boards comprising said stairway creak, and you notice that they're stained red with blood, though it looks like someone tried to clean it up at one point in time. Shrugging it off, because you've already seen a disembodied head hanging from a hook and watched in agony as your companion fell limp to the ground after you yourself kicked it into a wall, you continue up the stairs and reach the room above, where everything looks exactly the same as downstairs. Chairs pulled out from under the tables, drinks and food lining the tables, no one in sight.
Behind you is the stairway
In front of you is the balcony
To your left are the tables
