Shard question

[Iscah]

(That actually solves the lore for AST in 5.0 when they might look at the stars from the First. We might want to look carefully at thos job quests)

That shouldn't be an issue either way. If the shards are entirely split universes, they're still copies of the Source and all the stars will still be in the same places.

12,000 years isn't a lot on an astronomical timescale, and I don't think there's much scope for random variation, at least regarding what the night sky will look like (but you'd have to confirm that with an astronomer). The stars will continue on the same courses according to gravity and motion.

My thinking on this is the answer is it was a localized thing only though how creating extra mass and matter didn't cause any ripple effects of moving other planets out of alignment is beyond me. What's also not known is if you can see any of the remaining shards orbiting the source or not or if they're invisible and they just create a huge blackness to on lookers around the Source.

I don't think they're physically in the Source dimension though. No extra mass was created there, and you can never physically see from one to the other. It's more like reality itself has split into multiple threads, and each is equally real and alone from its own perspective.

Though if the split is localised, I would guess that maybe the Source is the only one you could actually arrive on if you travelled from elsewhere in that universe.
