The Zi'yuji Universe is a universe that was discovered in the early days of the First War, in the year 1599. This universe (and its' pocket universe) is where the species such as the Lombaxes, its' unique technology, and Ratchet came from. The Gear War took place here also, with said conflict being the primary reason that prompted the Lombaxes into joining the Alliance, allowing the First War to erupt in this universe. It is classified as "The Remains" universe
