Wll there ever be an explanation as to what the pixies really are, and why and how they keep turning into unintelligent beavers? (They're clearly not the souls of children, as a pixie shows up in Elpis and turns into a beaver later, so they're presumedly an Ancient creation, but the reasearchers there didn't even seem to know what they were or where they came from).

And on a similar note, what was up with the infamous shoebill which followed us around the First in Shadowbringers? I know it was long theorized that it was either Emet-Selch's familiar, or an avatar of him (given weight by the shoebill minion that drops in Amaurot), but it also again shows up in Elpis under test, and again no one knows who created it or why. So this mystery is another thing I'm dying to uncover the truth of!
