Under a Broken Aegis (Xenoblade Chronicles 2 AU) by AeroAegis

Summary
What if Amalthus awoke Mythra instead? What if the personality that corrupted Malos' will corrupted Mythra's instead, leaving Addam, and therefore Rex, with the Aegis of the Endbringer, rather than the Lifebearer?
An attempt to faithfully rewrite the story of Xenoblade Chronicles 2, with the change of Malos in Mythra's place. In Pyra's place, is an Aegis with water abilities known as Typhos. Malos gains the belief that his power of destruction is unneeded in the world, and dilutes it. Addam sinks Typhos in the Tornan warship, as he did with Pyra, only for its contents to resurface due to the aid of a certain salvager.
"Just as flames beget light, all that lies in the depths of water is pure darkness."

Summary
It was supposed to be a simple job. Work with the team, haul up a giant ship hundreds of years old, don't ask questions, and get paid hundreds of thousands of gold. Honestly, Rex should have expected for SOMETHING to go wrong. Now he has everything he needs to achieve his dream of reaching Elysium, but come on, Malos could at least TRY to be a little nicer. They're Blade and Driver now, after all.

Summary
“Rex! When you come up against an enemy that’s too strong for you, what do you do?”
“Uh… Run away?”
“No, you dumbarse! You sneak up behind them and stab them in the back. Do it right here in the middle so their spine snaps. That way they can’t run or fight back.”
“…I’m gonna go puke now.”
When you’re up against someone with the power to bend reality, you have to fight dirty in order to have a chance. As Rex, Malos, and Nia begin their journey to kill the She-Demon permanently, they encounter new and old allies who join the hopeless fight. And together, they find a way.
Edit: I’m so sorry! I forgot the 2 in the title!

Summary
Amalthus happened to choose Mythra instead of Malos, which led to many changes in Alrest’s society, some for the better, and some for the worst. With Malos being on the side of the heroes and other, much bigger forces coming out from the woodworks, the journey to Elysium transforms into one of growth and healing. And when the heroes realize who they’ve been up against all along, will they rise up to the challenge? Or will they fail and let the world fall under Her iron fist? Read to find out!
Small edit: I realized that because Rex’s age is 15 in canon, some people might be uncomfortable with some of the tags. Don’t worry, Rex is 20 years old here!

One was awakened by a madman.
And the other became the Blade to a hero.

Summary
(“Who exactly...are you?”
“You may call me...Alvis.”
They stood with their eyes locked on one another-gold meeting silver- neither moving an inch. And somehow the scene felt so familiar to Rie, like a long-forgotten memory gnawing at the back of her mind.)
OR
Ontos never leaves, instead it is Logos who gets warped to another dimension. And like a stone cast into a large body of water, the ripples are felt everywhere. By everyone.
