This is the first achievement you'll get in the game.
As you start the game, you will see a white expanse, with a side-table and a door in front of you.
When you get to the side-table, you'll see a bowl outlined in yellow, with a set of keys in. Press
near the bowl. You will see a man take the keys, and fade out. Go to the door, and you'll see the man reappear, and go through the door. This achievement will then unlock.
