November of 3049, Valcarol’s people land on earth and plan exploratory missions. Will there be clean air and water on earth? Will there be people there to help them fix their ship’s hydro system? Will it be safe outside of Valcarol?

One of our explorers has met a survivor on earth. This survivor gives us the secret location of their water filtration station. It is protected in a cave system that was used as a fallout shelter back when the bombs rained down. This cave system has the special element that makes radiated water clean and safe again. The survivor is to remain anonymous and will not accompany us. We are going to the caves at our own risk. Volunteers for this mission must enter the caves while security is off the premises and make it through any protective measures. Find the elements that purify the water, including the special element that is mined from the cave. Once all of the elements are found, bring them to the water filtration system and get it working. Security will be gone for only an hour, so be quick! This is an important mission because clean water is needed by the dehydrated people of Valcarol and our hydro systems engineer will need to recreate the cave’s water filtration system that can put Valcarol and her people back into space.
