In this quest, Theresa tells you to go to the Temple of Light to recruit the Hero of Strength. When you speak to the head monk, he will tell you that he needs help with an important job, but that he cannot trust a total stranger. You must increase your renown to please him. Once your renown is high enough, he will consider you for the job. Apparently, it is time to plant the next Golden Oak. Temple Tradition requires that the seed must be watered by water from the Wellspring of Life. The Wellspring of Life is in a cave that is supposedly very dangerous. Temple Tradition also requires that only two people may go in to retrieve the water. The first must be the strongest monk in the Temple. The second may be any monk of the head monk's choosing. Instead of this second monk, the head monk wants you to go in to protect the strongest monk, Sister Hannah. Hannah also happens to be the high monk's daughter. He sends you to meet Hannah, called Hammer by the other monks, by the mouth of the cave. When you go to meet her, she begins to complain of the boredom of being a monk (and doesn't ever seem to stop). She picks up an enormous golden pot and tells you to lead the way.
As you enter the cave, a hallway takes you into the central chamber. The other three sections of the cave branch off of the central cavern. When you enter the first cavern, Hannah notices the beautiful Wisps that hover near the cave's ceiling. You pass through without incident, until you reach the spring itself. Hannah stands on one marker, and you must stand on the other. This activates the water flow, which slowly fills up the pot. After you finish in the first room and begin to exit, some of the wisps plummet down in the ground, only to dig their way back up as Hollow Men, which are undead-like creatures. You must fight them off with Hannah, who is forbidden to fight by monk regulations. Once you reach the central chamber, the wisps stop following you.
You then head into the second area. After a short walk, you end up in a room very similar to the first, only this time, your marker is much farther from Hannah's than before. As you fill up the pot, Wisps continually form Hollow Men that charge at Hannah. You must fend them off until the pot is full. When you return to the central chamber and attempt to enter the third and final room, the gate into the room shuts down before it opens enough for you and Hannah to enter. Your dog runs through, and after several seconds of silence, comes back holding something. Upon examination, you find that it is a Hollow Man's head. The gate then opens all the way, and you continue through. Along the way, the Headless Hollow Man attacks, and acts as a minor boss, being much more powerful than the normal Hollow Men. After you dispatch all the Hollow Men, all you have to do is bless the water, which Hannah does for you. After fighting off several more Hollow Men, a monk enters the room through a back door saying that the Temple is under attack. Hannah immediately drops the jar and picks up a hammer from the nearest statue (Hence why they may call her 'Hammer'). You follow Hannah to the Temple, where you show up just in time to watch the head monk, Hannah's father, be killed by a dark humanoid, one of Lucien's men. Hannah then kills the humanoid, crying, "You idiot! You stupid fool! I could have stopped this!" and the scene ends.
You then appear at the head monk's funeral, where Hannah and two other monks are to dedicate and bless him. Hannah is despaired at the monks' belief that everything will go back to how it was, and sulks as the other monks leave. Theresa then shows up and offers Hannah a chance at revenge. As they teleport to the Hero's Guild, Hannah tells her, "Call me Hammer". The scene ends with a golden acorn planted at the head monk's grave.
