RWBY: Remnant in Earth.

in december of 2022, gold miners found a cavern filled with strange crystals deep within the mines of California. this discovery brings about the merging of two worlds: remnant and earth. However, even if the two worlds combined as one, the unity between remnantians and terrans are questionable due to old opinions, history and beliefs.

so it's only a matter of time for the leaders of the combined worlds discuss on how they should proceed on without breaking out a full scaled war on all sides.
