Millennia Ago and Now

RWBY and Bionicle, right now it's my take on the backstory.

Disclaimers: I own nothing, the ones who made it are the real owners

Bionicle Universe

"Gather friends, listen again to our legend, of the Bionicle. In the time before time, the Great Spirit descended from the heavens, carrying we the ones called the Matoran. To this paradise, we were separate and without purpose so the Great Spirit illuminated us with the 3 virtues, Unity, Duty and Destiny. We embrace these gifts and haven so we name our island home, Mata Nui after the Great Spirit himself."

"But our happiness was not to last, for Mata Nui's brother, the Makuta Teridax was jealous of these honors and betrayed him, casting a spell over Mata Nui who fell into a deep slumber. The Makuta was free to unleashed his shadows and unleash them he did."

RWBY Universe

"But in Millennia Ago before Metru Nui, Mata Nui, Voya Nui, Mahri Nui, Karda Nui and everything else that came before and after that, there was the world of Remnant. This planet's inhabitants are organic beings called Humans, these humans live in kingdoms and lived a very peaceful life. One hero by the name of Ozma arrived at a castle to save a beautiful woman name Salem, various heroes failed to save her but Ozma was the only one who succeeded, after this Ozma and Salem became lovers and lived a happy life together, unfortunately this didn't last long because Ozma dies from illness leaving Salem with a lot of grief."

"Salem however was unable to accept this and the fact of life is we are born, we live and we die. Eventually Salem brings Ozma's lifeless body to planet inhabitant's creators, Light and Darkness, Salem first starts with Light who rejects her request and sends Ozma's lifeless body to the afterlife much to Salem's dismay. Light then Salem away after this, Salem then went to Darkness who eventually accepted what Salem wanted and brought Ozma back to her before getting interrupted by Light resulting a brief fight between the 2 Gods. In the end Light was able talk some sense into Darkness who apologies to Light and sends Ozma back to the afterlife in the end."

"For Salem she was given immortality which means she is unable to die before being sent away again. After many failed tries to commit suicide and die Salem later convince the leaders from each Kingdom to view the Gods of Light and Darkness as a threat to humanity, Salem gather the leaders and their armies against Light and Darkness but fails to destroy them and humanity was purge out of existences all accept for Salem, the last thing was done is Light and Darkness left the planet but Darkness accidentally damages part of the Moon."

"Meanwhile Light was able make contact with Ozma who wishes to join Salem in the afterlife but not before being told everything that has happen while he was in the afterlife. Light told Ozma to find the relics so that humanity will be judge one day. Ozma eventually returns to Remnant and saved several people that were being attacked by the creatures of Grimm before reuniting with Salem who appearance has changed after falling into dark pool of magic, it's dark magic."

"In time Ozma and Salem began saving Remnant from all of Grimm and the people including a new breed of humans known as Faunus began worshiping them as Gods. Ozma and Salem are enjoying their happy life together again with their children but in time Ozma began to questions things and eventually he and Salem became enemies. After the breakaway Ozma now renaming himself Ozpin needed ideas on how to kill Salem, sadly Jinn from the Lamp said there is no way to kill Salem much to Ozpin's dismay."

"Regardless Ozpin vows to form a force known as Huntsmen and Huntress to oppose Salem, her Grimm, and evil Huntsmen and Huntress. Sadly this didn't go to well due Salem's minions infiltration and including those who were allies suddenly turn into enemies due to corruption and poor decisions and resulting the collapse of Remnant leaving Salem and her minions to dominate the planet. While all heroes have fallen or disappeared into hiding, even those who the magic of the Maidens disappeared."

"Unfortunately that wouldn't last long anyway with the arrival of the Brotherhood of Makuta and the Dark Hunters who would eventually bring an end the Remnant Era and beginning of the Bionicle Era, what was the world of Remnant is now the world of Bionicle."

End

For the record was never going to do RWBY Fanfics ever again, I gave up on that because of new characters on each Volume I watch that cause me to get lost. Was else that cause me to get lost is many characters who were Ruby Rose and her friends allies suddenly become Antagonist/Villains. In the end if I ever felt like doing a RWBY Fanfic everything will be Non-Canon.

The Toa Nuva's Armor appearance here will be during the Battle against the Bohrok-Kal and the Rahkshi. I will also including the Toa Mahri here. What else the world Remnant will be actually Aqua Magma.
