Documents from Lab X18, part 1

 is a storyline quest item that appears in S.T.A.L.K.E.R.: Lost Alpha. "Teleportation; there’s few tailored definitions or technical theories on the actual science of doing it. Realistically the problem isn't impossibility, but how to circumvent the laws of nature - a truth, but not an irreversible finality - to create wormholes. However, the research of the other laboratories have yielded “strange stones” with extraordinary properties that - if controlled and applied properly - makes teleportation and other such feats possible! I’m sure of it, even if it a wild theory in my head. I have to write down some diagrams and notes to demonstrate the concept… I can only imagine what would be possible if other types of these “artifact stones” can be manufactured."
