Okay so in sun moon she said she was protecting some kind of tower before appearing through a wormhole.

It cant be megalo tower. She has no connection whatsoever to urs in usum.

So it can only mean battle tower. But battle tower is not in trouble in emerald. It doesnt even exist yet in oras.

But it did get attacked in one of the mangas. So theoretically this Anabel is from the manga universe.

And thats why she has no role in usum. Cuz shes a character that is irrelevant in the game universe.
