The castle is supposedly very old, which means it may have some remnants of the Ancients. If we're lucky, we might find something to help us understand Crystallis better.

[With Scholar equipped, Jade would be able to read Ancient, should they find any texts inside.]

I doubt we can cover even half of the entire castle on our own, but there will be other groups to carry on where we leave off. We should focus on being thorough with the areas we explore.
