Dark Fact's army begins their assault on the remaining human settlements as Adol continues up the Tower of Darm. In his throne room, Dark Fact tells Dalles that he turned to evil because he feels that humans do not deserve to be saved. Below them, Adol reaches the second highest floor. Feena tells Adol to touch one of the mirrors in this room to teleport to the throne room, but before he can Dalles appears and attacks. Adol defeats Dalles, who is apparently vaporized, and continues on. He finds Leah and saves her, allowing her to return to her sister. The two goddesses then teleport to another section of the tower where Dogi, Ruben, and Goban are and thank them for all they've done. The five then teleport to the throne room and confront Dark Fact. Dark Fact accuses the goddesses of causing all this evil by giving humans the Dark Pearl, the artifact that allowed them to harvest claria in the first place. Goban and Ruben step up and argue that it is human mistakes that caused the evil, not the goddesses. Dark Fact laughs and teleports out of his throne room, saying he must go fight Adol and doesn't care about the rest of them. On top of the tower, Adol and Dark Fact battle while below the goddesses destroy Dark Fact's throne and reveal the Black Pearl. They sacrifice themselves in order to destroy it, which instantly kills every monster on the island. Back atop the tower, Dark Fact realizes this and drops his sword. He tells Adol that the world is saved and that good has triumphed. He then asks Adol to kill him as that is want he wanted as well, and if he is not killed than the darkness will force him to continue to fight for evil. Adol hesitates, but then kills Dark Fact, prompting the priest to thank him before he expires. The final tome, the Book of Fact, appears and Adol claims it. The six books light up and their power destroys the vortex around the island, restores Sarah, and teleports Adol to the floating island of Ys...
