The term Maker refers to a being that created the fal'Cie in Final Fantasy XIII and is said to have created the world of Gran Pulse. Eventually the Maker departed the world, beginning the events leading up to Final Fantasy XIII. Hallowed Pulse is the name given to the Maker in certain Analects discovered on Pulse, and the world is named after it.
It is possible "The Maker" is a term which does not refer to one deity in particular. For Cocoon fal'Cie, their maker is Lindzei, while for Gran Pulse fal'Cie, their maker is Pulse. It is implied both lots of fal'Cie wish to be reunited with their respective makers. Another figure the term "Maker" may refer to is Bhunivelze, the god who is said to have created Pulse, Lindzei and Etro. In that retrospect, Bhunivelze is the creator of the world and all things through his three creations.
The Final Fantasy XIII Ultimania Omega further confirms that the fal'Cie are looking for their respective gods, further implying that "Maker" does not refer to a single being. The fal'Cie in Final Fantasy XIII are said to have a common goal of finding the door to the Invisible World, but the Final Fantasy XIII Ultimania Omega suggests that even if they found it they might not find their Maker, and that the gods could have manipulated the fal'Cie to make them want to meet them, and thus search for the gate because the gods themselves wish to find it.
The main scheme of the villain of Final Fantasy XIII, Barthandelus, is to destroy Cocoon to call the Maker back into the world. The fal'Cie believe the Maker has gone past the Door of Souls, the gateway to afterlife. By killing millions of people at once, the fal'Cie believe the surge of souls flowing through the Door would "throw it wide open".
The main cast in the game do not know about the Maker until late in Chapter 10. When they encounter Cid Raines in the Fifth Ark, Raines explains how the fal'Cie want to use Cocoon as a sacrifice so that they can get the Maker to return. However, the fal'Cie cannot destroy Cocoon themselves for they are bound to its creation and maintenance, so instead they use l'Cie as tools and give them the Focus to destroy it in their place.
Later, Barthandelus presents them with a choice — they can either allow Cocoon to destroy itself from within through the conflicts between the Pulsian beasts, the Cavalry and PSICOM, or confront Orphan, the main fal'Cie that holds Cocoon in place above Gran Pulse, and allow the world to die painlessly. Upon return to Eden, they discover strange crystal dust in the air that Barthandelus claims signals the Maker is soon to return.
When the party destroys Barthandelus, it awakens Orphan and the party finds out Orphan's goal is the same as Barthandelus's. After Orphan's destruction, Fang and Vanille save Cocoon by becoming Ragnarok and erecting a huge crystal structure to stop Cocoon from crashing into Gran Pulse. Thus Cocoon is not destroyed and the return of the Maker is prevented.
- In the Japanese version, the characters refer to the Maker as "God".
- Before International release, Maker was incorrectly romanized as Moktar.
