First off, my condolences to you & your family right now.

I'm curious though, when did her fascination of space & simply the moon grew during her time around? It's wonderful to have hobbies & interests of many different subjects, yet for this case how can a hobby really be a part of missing appearances of someone in general. Absolutely terrifying to really think about, but to stay grounded of this situation they're always "something to start from" . Could be a human with a shitty motive or entity we cannot even see like some children do very well.

Idk my guy once again I am sorry this is happening to you really.
