Lightkeeper/Keeper's Word

I have a new job for you. Someone found a way into the cellars under the health resort. This is not a good set of circumstances for Tarkov. Excessive curiosity often ruins a man in peacetime, but in the present situation, the mistake of one will lead to the death of many. I know how to safeguard the bunker. You may not have yet met the wardens who watch the city at night. But they certainly have met you. And now I need you to leave a short message for them at the Knossos facility, with their instruments. However, just dropping these knives in the rubble won't be enough. You need places with meaning, so that the knife you stick in becomes a symbol of sorts. Which places should you choose? You'll figure it out on your own. And if you can't, why should I even work with you?

Perhaps now you've saved Tarkov from a new calamity that could have wiped the city off the face of the earth... before its time. Your reward is here. Oh, and one more thing. If I were you, I'd stop enquiring about those dungeons if you want to survive these troubled times.
