So, just as a heads up. I kinda have a plan for how the big bad gets taken down. It's going to take a bit of time and for this version of Amelia to get some serious character development first. Plenty of opportunities though for side stories, particularly as there's a literal whole other world of alternative characters that could be entering and causing havoc in the main world.
With that in mind, I'm guna keep encounters with the main villain to a minimum. But her appearances will almost always be brutal/devastating. xD In the meantime, she'll mostly be sending her loyal lackeys to do her bidding.
