She explains to you how she has been trying to get a lightning bolt to strike the metal rod, and through the wires connected to the rod, bring the dead humans in the tanks back to life. She needs an extra pair of hands to help with the rod, and wires, etc.
After many days and nights of hard work, the doctor finally feels ready to try to reanimate the dead. The next day, a huge thunder storm blows against the tower, and to your delight, the lightning from the storm works: everyone opens their eyes inside the tanks, and you run around with Percy screaming with joy and open up all the tanks to free the people.
A new civilization is born, and you and Pirate Percy live together with your undead comrades happily ever after.
The End
