If it isn't for the humming of equipments from inside the building, you would have thought that this place is abandoned. The leafy ecosystem spreading on the concrete wall seems to be in good condition. After going through the main door, you find yourself in a welcoming room that looks like a hybrid of lounge and office. You notice a hand-drawn map on the table, it is weirdly artistic and clearly labeled. A small note is written in the corner: 'Just in case you get lost :)' Signed: L.
