The Agent asked you to use all your resources to get the wise man from the Tower of Eternity to Esterra. Dezabo, the wise man of the Tower, wanted to take a look at the situation in Esterra first. He needed help because he didn't feel well outside of the Tower. You helped Dezabo and examined the Aether Pieces scattered throughout Esterra to learn more about how they affected Esterra. You reported to the Agent. Since the fragments most likely come from the Tower of Eternity, one can probably use them to restore the Aetheric Field. She was very happy about this news.
