You and and another guy were sent on a mission to check on the status of a far away hydropower-dam that your main base had lost contact with. So far, you are 600 miles away from your main base and about 20 miles away from the dam. You and your partner ran into a situation that had you fighting for your lives against raiders, and in the end, you both made it out of the conflict safely. A peculiar vile containing a strange liquid had been looted from the dead raiders before resuming your trek.
