Yeah! cuz ya know that, right? ya know daughter, orphan, children, get it?
Well, for all I know, an orphan is someone
without a parent.
From http://www.imperial-library.info/obscure_text/vehk_teaching.shtml:
...according to the texts, Mnemoli is a wayward child of ANU, one of a pantheon of forgotten deities known as the 'Star Orphans'... a tribe of gods and goddesses that apparently felt abandoned when the Sun Withdrew from the World-Making.
Why would they be confused when Magnus left, if it wasn't because they were left behind (=orphaned?)
And even though Mnemoli is described as a "Blue Star", she clearly isn't a "star" in the same meaning as all the other ones up there, because:
1, It is blue, while the other holes to Aetherius are characterized by a bright, white-yellow colour and light.
2, It is moving around (whenever it can), and I believe that the general consensus is that the "usual" stars are fixed in the sky?
