Yes, at first I want to make her as a Rider, but because I was seeing people did it in Hitsuji's blog (not from Hitsuji, but still count), the fact that she is from "The Root" or actually a living weapon from alien just like Altera (or just "alien who somehow hijack Amelia's body"), is still debated in the lore, even other characters point it out.

Yep, so how, her plan can travel into another dimension, and it's has appear in her iconic airplane, but in form of "Nebula Light"...but after her ascension, it would have a appearance of "cool ship that come out from Mecha anime" instead.
