What is Lucrezia's end goal?

It's been a while since this subreddit theorized about this, and I've been doing a re-read.

We know:

- She disappeared when Castle Heterodyne was attacked

- She's the Other, commanding an army of revenants

- She killed the god queens

- She time traveled

- She possessed people

- She's knows a lot about the queens' mirrors, technology from before recorded history

I think based on the extra dimensional shenanigans we've been learning about since the cultists in England, some form of Lucrezia has been hanging out in the dreen dimension, which allows her to travel time and be "summoned." But she doesn't seem to understand the Dreen vs. Chronokaiju fight at all...maybe another dimension?

But to what end? To become a god queen? Then why hasn't she yet (can't find a flame in all those thousands of years I guess)? To rule the world? Seems more reason to me, but all this time travel seems awfully convoluted. I'm mainly seeking a more solid connection between the queen-murdering (seemingly worldwide) and the Other takeover (Europa-focused so far).
