Adventurers needed to retrieve an arfitact to help solve this zombie problem.

The adventurers were sent off by the king of Vesuna to retrieve an artifact of positive energy in order to close the rift in the city created by Koth that was raising zombies in the city. They ventured to a distant island and explored an abandoned magical research facility, where they recovered a large white orb, which (after blowing up the facility) they returned to the king and ended the zombie crisis.
