Hey! It’s me again! I notice you like Code Geass too!
Actually in my Narnian/Ransom Trilogy fanfiction multiverse and I have a reimagined Code Geass AU as well
Code Geass: Lelouch of The Knighthood which is mostly inspired by Prince Caspian
It exists as an alternate earth which like the D.Gray-Man world shares a singularity which is The Birth,Death, and Resurrection of Christ which redeemed all worlds
In it Suzaku was framed for his parents assassination and his memories rewritten as a child, this was the work along other political figures throughout the world getting assassinated(including Marianne along with Lelia and Empress Tianzi’s parents) in a satanic conspiracy of The Geass Order lead by Vincent(insert Freemason joke here) under their service to “The Usurper of Geass” who’s implied to be Satan/Tash/The Bent One
Soon this leads to Charles own death when he regrets what he’s done and finds out about Mary’s death being part of the cults plan and is about to tell the public and Schnizel taking over with a satanic mockery of Geass with the aid of V.V. to continue the scheme
Here Aslan/Christ appears as cloaked and masked figure “The Master of Geass” son of “The Infinite One” and through whom “The Geass Specter” proceed through
And the Keeper of Space Time is the Oyarsa of this world if your familiar with The Ransom/Space Trilogy
Geass in this case is the configuration of “Deep Magic” of This World and given how C’s world works, it can kinda be how the communion of Saints manifests itself in this world and tragedy befalls only to those who try to bend it to their will rather than submitting to the Master, kinda was inspired by The Magician’s Nephew
Basically Lelouch and Co make better choices(there’s still drama and conflict mind you!) and their major goal is to get Nunally seated as Empress and stop The Ragnarok Connection which is far more demonic in this AU
I’m just thinking how Aslan would get to Lelouch, Suzaku, and Kaplan with their bitterness and sorrows. Lelouch definitely needs work with the wounds of betrayal, and hoo boy is Jesus not unfamiliar with betrayal and suffering
That's a lot information to digest so I took my time thinking and answering this ask. I must say you put a lot of mind and efforts into this fanfiction of yours. Such enthusiasm is admirable, so keep up with it and don't let what I share next be a guide to your brainstorming and world-building. I believe one remains a better judge for one's own writing, for good or for bad.
I have zero knowledge on the Ransom Trilogy, so little can I contribute on details related to it. I do love Code Geass, though; so I can share a bit.
In my opinion, Code Geass is a story about the battle of philosophy and ideologies which ends with the triumph of the protagonist's, Lelouch's, idea, which bears the closest resemblance to Christianity. Unlike his father Charles or his brother Schneizel, Lelouch chooses the role of a villain to be slain instead of the role of God (funny, as the Son shows Himself to us not as the dominating Lord, but chose to follow the will of the Father to be the sacrificial Lamb to take away the sin of the world). He offers himself as a sacrifice to give the world a chance to embrace the future and puts his trust in people's perserving wish for happiness, and death is also his way of atonement. Despite all his lies and faults, Lelouch is quite a romanticist who never gives up his belief in hope and dreams, who treasures his loved ones, who, to quote Chesterton, "hate it [the world] enough to change it, and yet love it enough to think it worth changing." For such a character, I don't think it's hard for our Lord to reach to his heart. The only issue is whether he will accept our Lord's will, which asks him to entrust everything to the Divine Mercy.
Suzaku is the obstinate one here. While I also love him as dearly as I love Lelouch, after losing Euphemia, he acts like a jerk (partly justified), and only after committing the irreversible crime of robbing the lives of over 10 mil people that he accepts Lelouch's method and wholeheartedly works with him for the greater good. Still, I understand why Suzaku stubbornly clings to his idea, and he's right in thinking that the ends cannot justify the means; though frankly I think his means are also controversial and contradicting to this particular belief. Anyway, how God touch his heart depends on at which point Suzaku is at that time (the naive suicidal boy before meeting Euphy, the man full of anger and resentment after her death and betrayal to Lelouch, or the massacrer of millions).
Lelouch and Suzaku make the best choices with what they have to deliver a good story; not necessarily the wisest, but most appropriate given their personalities and surrounding circumstances. Now the thing with stories and fanfiction is that I love them because while they are somewhat similar to the real world, they need a bit of naiveté and idealization to let everything fall into its place and bring about the wanted outcome. You have chosen the hard task of bringing God to your fantasy universe as the only thing equal with such experience is our real life, which will last till the Day of Judgment. Best to quote Tolkien here:
“... Actually I am a Christian, and indeed a Roman Catholic, so that I do not expect ‘history’ to be anything but a ‘long defeat’— though it contains (and in legend may contain more clearly and movingly) some samples or glimpses of final victory.”
(JRR Tolkien, Letters, 255)
I object to the idea of a masked and cloaked figure. That reduces Jesus Christ to a mere symbol while unlike Zero, He is the Way, the Truth and the Life, the Word in flesh and blood. To have Him hide behind any kind of mantle seems tasteless and defies His nature.
I'm also not comfortable with the idea of Lelouch doing his best to put Nunnally on the throne. While she is more than capable, I doubt Lelouch would place such a heavy burden on his dearest sister's shoulders. It's one thing that the situation forces him to let that happen or her to take on the responsibility by herself; it's totally another thing for him to treat it as his original goal. Lelouch loves Nunnally too much to do that.
Hope you find my answer helpful.
