SPOILERS - I have questions about calamities and the order of events from DT

So it could still theoretically be that their world is the twelfth, and that Living Memory is a bubble world existing outside of the shards and source, surviving off the aether of other worlds?

about that:

As the credits began to roll you see the barrier dissipate to show an UNTAINTED atmosphere, and the realm did not implode. This implies not only a reflection that is whole, but one that has HEALED and potentially has healthy societies elsewhere to explore. This subtle bit of hope was a nice touch that makes me less angry at the glaring continuity issue of the levin bubble persisting after the events of the 2nd trial
