The release of Final Fantasy 7 Rebirth Ultimanium has confirmed that the game introduces multiple universes, which will be explored further in Part 3. Stamp’s breed serves as a key metric for differentiating between these universes, with a total of seven different worlds being introduced.
The story becomes increasingly complex with its multiverse shenanigans, prompting the need for extensive time and effort to follow the events. However, the Ultimania has provided clarity on these concepts, and promises answers in Part 3.
The book reveals that we switch between two of the worlds to experience the trials and struggles of Cloud and Zack. Additionally, it clarifies that there are more than just the two worlds we have seen.
Stamp’s breed is identified as an indicator for determining the world being depicted, with distinct versions of Stamp representing different universes. The game’s ending has set up a total of seven different worlds, presenting a fitting number given the complexity of the game.
It remains to be seen how Part 3 will make this complex narrative understandable and bring closure to the story.
