In the FF14 universe, Tactics happened a long time ago and the FF12 Ivalice is a part of Hydealyn. However, just as there are infinite multiverses, so lies the possibility they aren't THE Ivalice from the original games. But since we didn't know anything of "the world beyond" Ivalice in Tactics and FF12, it could go either way. You could think of it as a different multiverse, or that it has always been a part of Hydealyn. That's the nice thing about FF series, is that a lot of it can cross over.
Omega and dragons are from another planet, technically. The other shards are seemingly part of a multiverse that was created when Zodiark was expunged and reality broke, and other beings like Ultima(and crossover characters, I guess) are from another plane altogether.
