Remnant. Several years ago, Infinitus Prime/Ian Prince and Task Force Disciples arrived at this realm currently in turmoil with numerous problems such as the Grimm, White Fang, banditry, racial discrimination towards the Faunus, and the secret war between Ozma/Ozpin and Salem. A world that Ian and his forces managed to fix and solve its problems, including Ozpin himself, who went mad after making a deal with Quintessa and was given an appropriate punishment following his reincarnation ability being removed by Ian.
But, what if Infinitus Prime/Ian Prince and Task Force Disciples didn't arrive at Remnant and solve its problems? In this alternate Remnant, the secret war between Ozma/Ozpin and Salem was still ongoing and the Four Kingdoms were rife with numerous issues such as the Grimm, White Fang, banditry, and racial discrimination towards the Faunus. However, in this alternate Remnant, there's in fact a Fifth Kingdom, hidden from the main Four.
However, this Fifth Kingdom does not call itself as such, but rather, it is an Empire. One that is far more superior to the main Four, including Atlas. Its name is the Imperial Federation of Reach and from this Empire came Auroa, a warrior princess and the Crown Princess. Joining forces with Team RWBY, JNPR, CFVY, STRQ, and Glynda, she would solve Remnant's global issues and end the war between Ozma/Ozpin and Salem once and for all.
