Ignored Alexandria because is not part of Tural and it has a simple yet convoluted story to to shard/time travel shaenigans: Lalas discovered an omnimaterial for everything, countries went to war for the control of that rare material, rejoining happened, a fragment of the shard survived with their tech and recreated the fallen princess as an AI. Also eventually started to digitalize people when they died but the maintenance costs gradually scalated, at the same time they started using souls as a fuel which allowed to have extra videogame lives to avoid untimely deaths. That created an unsustainable system that would eventually collapse on itself because Sphene was unable to let things go
