the car takes you to your requested destination.

and the man that handed you the envelope shows you to a subway entrance and accompanies you to an unmarked door. he swipes a card and opens it, and before showing you inside, he reaches inside his jacket and pulls out a gun.

inside is a long corridor and signals for you to follow him hastily. half way down the corridor he stops in front of a closed door and again swipes his key card.

as he opens the door and follows the barrel of his raised gun inside, and starts to shout at some one inside, he shouts something in a language you do not understand, probably dutch. the men inside the room rush to their feet and exits as fast as they can without any attempt to resistance.

inside is some kind of control room with several monitors with live feeds of various cameras. there is only one other door in the room and next to it a panel with a keyboard.

a prompt is ready to accept a password.

the man leaves you alone in the room. the last thing he says to you before he closes the door behind you is:

“it is up to you. you already have what you need. ten letter password from the path that led you here.“

you stare at the monitor and keyboard. what might this password be? and what does it unlock?
