Awaken in a dark room

Your splitting headache allows you to open your eyes only gradually. After a few seconds of gathering yourself together you realise that you are in a dark, poorly furbished room alone. In spite of your desperate efforts, you cannot recall how you got here. And even, your pulsing head beclouds the most of your memories. Where am I? How did I get here? Who am I? The racking questions remain unanswered. The room’s only door is locked.

When you turn to the source of the low light, you realize that it is illuminating from a laptop.

It is switched on. As you stagger closer you can see a single line on the computer screen:

System malfunction. Missing general value. Insert the universal value of life. _
