You see a dwarf and follow him. He feeds you and asks you if you wish
to help him build a tank. You say yes because he also mentioned to pay
you in berries witch are helpful for curing poison and work as
repellant against vampires. You get to work and finish building the
tank. The dwarf then goes on a tanking rampage and destroys the
civilization. You need to stop him. (not for the helpless people, for
the BERRIES!!!!) What happens next?
