Now that Luxu was revealed to be the traitor thanks to KHUX finale, this got me thinking, how will Luxu betray the Foretellers and MoM? This got me thinking what if I told you that inside the Black Box that Luxu was protecting is the 7 darknesses that MoM mentioned during his meeting with Luxu. This got me thinking, we never saw how the 7 darknesses possessed the Foretellers in the Keyblade War. Similar to how many people believed that the Foretellers died in the Keyblade Graveyard, yet we never saw their keyblades as gravestones. It would finally make sense why MoM told Luxu not to open it, the Black Box can only be opened at the right time and place. Well let's see the status of the 6 darknesses that we met in KHUX, who were stuck in the data world.
The one who escaped in the data world, and the one who interacted with Luxu and Maleficent. I think it’s the one that Xehanort sees and persists in spreading the Heartless to present day. But there's also a possibility that Xehanort will be possessed by one of the 13 darknesses. Since Xehanort has a strong heart there's a way to trapped the darkness inside his heart, since MoM told him that he will be a seeker of darkness someday (it was stated in KH3 ReMind). It would also give Xehanort to control the power to control the darkness.
The one inside Ventus who killed Strelitzia, and also escaped the data world. And the one who will gain a physical form named Vanitas.
And the four who were trapped in the data Daybreak Town by the Player.
So in other words, we defeated/killed the 6 lesser-known darknesses, that remains 7. But if you count the remaining 4 who were trapped in the data world, that remains 11 in total.
MoM said in his explanation that in order to kill the Darkness we need to:
Give the Darkness a physical form. (similar to Vanitas)
Kill the person who's been controlling it. (like Xehanort)
I think this was his plan, let the Foretellers be possessed by the darknesses. So that the 7 darknesses will gain a physical form, but one of them chooses to become a vessel for the Darkness, Luxu.
Luxu chooses to become a part of it because I think this is what the Master meant on why he called Luxu "a traitor", and he had foreseen it because of the No Name Keyblade which contains his eye. But I think the reason why Luxu would accept it is that Luxu never accepted MoM's plan to let his own apprentices and the Union Leaders become vessels for the Darkness. That's why Luxu went a different approach to accomplish his role, whether to meddle with the Dandelions (like Ventus, Brain, Lauriam).
This also got me thinking if Luxu is the only apprentice of MoM to accept the Darkness inside his heart, is he also going to be the leader of the 7 darknesses? Look closely at the 7 black pieces, the goat piece (Luxu) is in the middle, while the other pieces of the Foretellers are on the left and right sides. I could be wrong though if Luxu is not going to be the leader of the 7 darknesses, it could be the dark half of MoM as his new master. But the problem here is the other members of the 7 Darknesses are just dark counterparts or abominations of the Foretellers. The thing here is according to MoM, what he read in the BoP "the traitor has a purpose". What is Luxu's purpose for doing this? What's his endgame? What's his plan?
It would finally explain why MoM is in Quadratum, possibly looking for Sora to "team up" with him to defeat the 7 remaing darknesses. The sad thing here is in order to kill the darkness inside Luxu, you're gonna have to kill him. Whether Sora or MoM will deliver the final blow against him. So in other words this is how the fight will happen:
Sora (and maybe his friends) vs Luxu
MoM vs Xeprus (dark counterpart of MoM)
Ira vs Dark Ira
Invi vs Dark Invi
Aced vs Dark Aced
Gula vs Dark Gula
Ava vs Dark Ava
I just hope the names of the Foretellers are also revealed because their names are NOT their real names. The names of the Foretellers are the names of their 7 darknesses. As for the name Xeprus, all I did is to rearrange the sigil of the Black Box XSUPER and I kinda found a name for MoM's dark counterpart.
But what do you guys think? Do you think this is how Luxu will betray the Foretellers and MoM and accept the darkness inside his heart? Let me know your thoughts and answers.
