How Is AST going to work in SHB?

[DamianFatale]

Can one open the gates of constellations in another reality? Are the stars different or the same?

How would they use their powers across realities? How can they function in a 24/7 day cycle? I have a feeling that the new quest lines will be interesting. They might possibly turn AST on its head.

The stars are the same in the different reflections, I imagine. 10,000 years isn't a long time in stellar terms, and while the FF universe likely does have beings which can affect stars, it's unlikely that they have.

Also, ASTs don't need to see the stars to use their power once they got it.
