I maintain that Astels are former humans which is why they don't look like weird tardigrate-jellyfish things like Elden Beast or Maris, Fathom of Night. I guess Metyr is a bit of an outlier, who knows.
The graven masses are described as "seeds of the stars" and Stars in ER are always used actually in relation to various living entities and beings. So, naturally, seeds of the stars would gestate into stars. They're eggs. They even have floating powers, so I posit that they would just eventually fly into space and gestate into Fallingstar Beasts, then come back to Lands Between.
Kind of vaguely matches how dragonflies lay eggs in water, too.
