I didn't skip any of the story but I may have skimmed through some parts out of boredom, so I would like to ask: did Krile even matter at all this expansion?

I don't remember her doing anything significant in the first half, then we discover she came from the city of gold and the one thing that leads into is her earring, which isn't used at all until the VERY END and even then doesn't immediately open the door since the baby is the one that has to do it. Did she do anything significant at all in any part of expansion? I mean, we meet her parents for 30 minutes and we learn a bit about another dead shard, but all that information is on terminals so even if we didn't have Krile we'd get that information anyway.
