The Water Guardian lies in Zariban, a desert land once fertile but rendered arid by the over-processing of energy stones. The party meet a clansman of the Saryu Tribe who by Yoshua's request leads them to his village. The village was suddenly destroyed by an attack by Kasadoll, a general and ruler of Zariban. He is after the Water Guardian and destroyed the village as the Saryu Tribe are holding the key to entering the Water Shrine. They manage to defeat him and gain the Water Stone. From the stone, they've learned that the last guardian is in Seirya.
