Also, of some interest...

It's in a spoiler tag because this came from datamining.

If I remember right, Arabella has been altered somehow by the idol of Sylvannus. I'm not sure how, but I think when she stole it, something happened. And that carries over into Act II. For what it's worth, I don't know if this is relevant, but it feels like it is to me, somehow. Like the idol is pretty darn important (outside of just being valuable), which makes the actions of these kids potentially necessary to the plot? Not sure, just a thought.

As of now, we can get three idols in the game. One for Sylvannus, one for Selune, and one for Shar. I think the one for Sylvannus is the only one that currently has any magical effect though.
