At the beginning of the game, if the fountain in the center of the town of Tristram is full of yellow-colored water, this quest is present in the game. It is initiated by speaking to Pepin after entering the dungeon for the first time. Completion of this quest will grant the player the Ring of Truth. The tainted water source is located in a sublevel which originates from the second floor of the dungeon. The entrance appears as an opening in the wall, and there are several candles nearby. Inside, there is more of the yellow-colored water. Once all enemies within the sublevel are defeated, the water changes back to normal, indicating the completion of this quest.
