[Back in her world, Eliza has put a lot of effort into hunting down Palkia and getting its help. That's a whole other adventure that might get described in detail somewhere else, but the end of it is that she's recruited the aid of a dimension-traveling dragon to get her where she needs to go. Hopefully you don't mind her popping in on you wherever you are. At least Palkia can also shift size so it doesn't crush anything by accident?]
